I want to say that I worry all the time, but I can't, because there are times that I don't worry about things for long periods. Usually the periods where I DO start worrying begin with a spontaneous Anger Attack with no cause, then I go downhill from there until a few weeks later, maybe months, where I go back to my normal hyper make-people-laugh mood.

Same as you, before a friend told me that it wasn't normal to worry a lot and to have huge shifts in mood and personality, I thought it was normal and that everyone had those periods of time... Then I started reading and learning, and now I've educated myself on what might be going on in my body.

My advice: Follow through. You must probably hate yourself for having so many disorders, but like me and my friend tell each other:

"At the end of every hardship there is something to be grateful for, be it a reward or the experience."

Maybe not THOSE exact words, but the exact message is still there.
