BELOW ARE LISTED SOME PROBLEMS THAT ARE SHARED BY MOST PEOPLE SOME OF THE TIME. IF YOUR "PROBLEM' IS LISTED, THEN READ ABOUT IT, AND HOPEFULLY JUST AN AWARENESS OF WHAT CAUSES IT WILL REDUCE IT AS A "PROBLEM".

ANXIETY:
Anxiety is most often an energy that one experiences when ones MIND is repressing some fear within itself. This fear has a particular vibration, and it can be stimulated by someone repressing this same vibration within themselves. So, if you are particularly vulnerable to this fear within your MIND, being exposed to it within another will stimulate your fear, and what you call anxiety is you becoming aware of your MIND repressing this fear within itself, and taking some of your "energy" to do this. Your anxiety is an awareness of your system "shutting down" in order to divert your energy to the repression of this fear within yourself. Perfectly natural, but disconcerting if one doesn't know what is going on?
DEPRESSION.
Depression is an interesting problem because it involves two emotions, not just one. The "problem" is not either emotion exactly, it is that this emotion is being stimulated at a level of intensity that your MIND has been instructed by you [at some time in the past] to not allow you to become aware of this emotion if it goes beyond a certain level of intensity.
What is going on within you is that, let us say grief is seeking to be acknowledged by you. But, unknown to most people is the fact that both Grief and Rage are opposite ends of the same MINDLINE. In other words, the >a href="MIND.html"> MIND has a great many MINDLines within it, and all the traumata one has experienced in all of ones lifetimes [and the emotional reactions to the traumata] are stored on these MINDLines... in pairs of opposites. And if one fears acknowledging some level of one emotion then its opposite [which is stimulated as well, is also feared. So, to acknowledge the one automatically acknowledges the other. And fear of either causes one to become "stuck" in repressing the emotion, and the energy required to repress this emotion causes symptoms that are labeled DEPRESSION.
That is, ones MIND has to rob ones energy to repress both of these emotions, and this causes one to get tired, irritable, fearful, and confused. All of these are just symptoms of ones energy being diverted to repression.
What taking a drug does is to chemically interfere in the brains ability to convey to oneself that ones MIND is under duress. The "problem" is not physical [although those ignorant of what the problem actually is, who are most often confined to intellectualism [research here], are unable to imagine that something they cannot "see" could cause some seemingly physical complaint]. So they readily reach for a drug to divert you from pursuing their ignorance any further. But perhaps it is unkind of me to point this out?
If one doesn't mind being dependent upon some drug for the rest of ones life...then the drug is your answer. HOWEVER....
To remove the "cause" of ones depression, one must find a competent Psychotherapist [one who has undergone exploring his/her own MIND, and eliminating the fears that were stored therein]. But, alas, finding a competent Psychotherapist today is a difficult thing to do.
So, what I recommend, if you are unable to find a competent therapist, is to find a friend. One who is not afraid of rage... and ask this friend to be with you, merely as an observer to insure that your rage doesn't make you disappear... just kidding! And then you practice your rage. It is not your rage, hate, etc., that is the problem. The actual problem is the pain behind the rage, and this pain is deeply repressed, and it is this pain that is being stimulated by something in your environment. But... whatever it is in your environment is not the CAUSE... it is only stimulating what is hidden within you. How to unlock this deeply repressed pain is the question?
It is possible to slowly walk oneself back in ones memory by writing in a journal, but this takes a rather strong personality. The process is thus: In the evening, take some time alone, and close your eyes, and concentrate on the earliest memories you can recollect. Don't judge them, or argue with yourself about them, just write them down as they come to you. Write for half an hour perhaps. Then, read what you have written, paying particular attention to any LACK of emotion where some would naturally be.
Dwell upon these missing emotions, because these are key to what your MIND is holding from you. Take the event, close your eyes, and go back to that event as though it was taking place at this moment. Allow yourself to feel any and all emotions related to that event. And keep doing this, night after night until you reach some deep emotion, and ideally, the pain you felt as a child relative to this event. This practice is you ordering your MIND to release to you what you ordered it to never release. So, it may take some time, but this memory is a "misperception" whose time has come to be released. Good luck, and remember, depriving yourself of your fill range of emotionality is painful. Who you are, at your Core, is a Perfect Soul. All the rest are bits of illusion that your MIND is confusing as reality.
Imagine your MIND being a puppet on strings, and your MIND perceives everything around it as real [this is the illusion of life], while you, holding and working the strings, represent the "Reality of Life". The MIND does an excellent job in what it does, but the MIND itself cannot perceive the Spirituality operating Life behind the illusion. It is not easy to rise above the illusion, but Peace can only be found in the Reality of Life. Peace is a natural experience of ones "intuition".
LONELINESS...
OR A SENSE THAT SOMETHING IS MISSING... Well, something is missing, and what that something is, a subtle awareness of ones Spirituality. In other words, the Attn Aspect of ones Apapsyche has shifted from ones Spirituality into the illusion, and one is "thinking", which invites ones MIND to engage in working through ones Karma. A very strange thing occurs when ones "attention" begins to make its home in the Left-Hemisphere of ones brain in order to avoid the pain of living on this physical plane. But you need to take a few minutes to research something about the concept of "attention" and you can do that here .
Ones attention is focused where ones Attn Aspect of ones Apapsyche is located, and if one is experiencing negativity, ones Attn Aspect must be in ones brain and thinking. The alternative to thinking is "intuition", and that is what one experiences by the Awar Aspect of ones Apapsyche. So, if at your Core, you are a Perfect Soul, and your Apapsyche is focused in the Left-Hemisphere of your brain, how would you expect to "experience" yourself? Of course we could play the game of my not knowing that you are a Perfect Soul, but let's not do that because I am correct I am also correct that as long as one refused to experience pain, and keeps ones Attn Aspect of Apapsyche locked into ones brain and thinking about stuff, one cannot help but be lonely. Peace
