I have a history of panic attacks ever since I was around 8 (I'm 16) and I think it developed into something much worse. I make certain things that I know has nothing to do with my life so important that it becomes out of control.  For example, I flush the toilet more than once because I feel that I didn't do it "good enough". I am obsessed with even numbers because I think odd ones are bad luck. It sounds crazy and I know it is, but I still think of it. I have a huge fear of my loved ones getting sick and dying, so I do certain things to prevent that. It's really bothering me! I bite my knuckle on my right hand where my middle finger is and I severely damaged my skin; I still continue to bite. What should I do about all of this? :-|
