SO CONFUSED!

Ok. So many things go on that I don't understand...I was eating stuff from under my toes just now and realized (even though I've been doing it for years) that THIS CAN'T BE NORMAL!!! So I searched and came across this..Don't know if I'm happy or scared that people do this. I also eat dandruff, scabs, blackheads, and skin.. Ugh...I can't believe I'm saying this...BUT This is not all... I got help over this summer because I finally decided to address ANOTHER issue that I had. I get really emotional from severly depressed to happy happy and then feel panicky. I was diagnosed with a slight case of Bipolar and then talked myself and my doctor out of that! Insisted I was fine and they all believed me. And I compulsively cut myself too even though I do NOT believe in that. Now I don't do this to get the scabs though. I do it when I'm angry with myself. Even though I know it's completely pathetic and wrong... Does all of this add up to me being crazy? I have no idea what is wrong with me! I have a great life, never been traumatized and everyone thinks I'm normal. But now I have yet ANOTHER thing to add to a list of things that aren't completely right with me. I just can't control my thoughts sometimes. Even though I know what's right from wrong!
