Researching Psoriasis

I've decided to do some research on psoriasis. I'm attempting to find out what treatment options are out there. I need something that works better then what I'm using right now. I found twelve websites that have information on the subject.

The problem is getting to me because I can't seem to find relief. Perhaps it's just a matter of finding something that works for me. Part of the problem could be stress, I didn't notice the issue with psoriasis before 2007 when my mother went into the hospital. Since then I've been under a lot of stress and the psoriasis seems to get worse. I want a solution or at least something to give me relief most of the time.
