When I was 20, I abruptly left my parents and moved into an apartment. We were having personal conflicts, and had I stayed, there's a possibility, however remote, that I would have been told by family members to see shrinks and take drugs (they didn't have enough money to have me committed). It was the best decision I made. Within two years I was working in the technology sector and I've never looked back.
Mental illnesses are often just political problems in the family, and if you can break free and gain independence, you can avoid a vicious cycle which leads to family members running to psychiatric drugs to explain away and suppress political issues.
Anxiety, depression and lucid dreams or paranoid thoughts are often the result of being in the wrong environment. I've had symptoms which, if I disclosed them, might be considered paranoid or mentally ill; but when I've changed jobs or moved to better environments, all of the symptoms have disappeared. I believe it's the body's way of telling you something is wrong out there.
Reading books can be a good way to take your mind off of difficult issues.
I would also eliminate caffeine and sugary foods from your diet.
I suspect I should cut my adderall and caffeine intake, eat healthier, get a more regimented schedule and excercise. Call friends more and try to get out and about with the few people I know around here
