I m 18 and i have been severly paranoid for as long as i can remember, as a child i rarely spoke, and as the years went by i developed extreme anxiety , and depression . My mood goes from being extremely hyperactive, to crying my eyes out for no apparent reason, to so angry that i terrify my parents, even though i dont Feel angry at all. i have conversations in my head all day every day, basically non stop. I used to be an A grade student, but now i find it hard to even concentrate on a book i m reading. I have tried to kill myself many times, and i dont know what to do. Please help me.
