Hi, I am a sixteen year old girl with some concerns. First of all I have Dermatillomania.  I have had since had since I was little but I only just found it's name. I bite my lips and fingers until they bleed, I pick at the bottoms of my feet until I can barely walk and I pop every pimple I get.  I have been trying very hard to quite-my lips and face are healed but my fingers are still awful.  I know that as soon as I become stressed again it will get worse, the only reason I have been able to quite lately is because I am on break right now so I am quite relaxed.  

So in junior high I was very outgoing, cheerful, calm, I had a lot of friends.  Now I go to high school with a lot of people I don't know and I have completely changed.  I'm a nervous wreck, I get angry very quickly, I am extremely passive-aggressive, I am unhappy.  I understand that it all could be due to hormonal imbalances because I am a teenager but I have been chronically unhappy and anxious for a year and a half now, which doesn't seem normal.  People at school are scared of me.  

I have also always had some strange behaviour since I was little.  Sometimes, for no reason at all something will happen, or someone will say something to me and I will get very angry or burst into tears of sadness.  This isn't your typical PMS type deal either, this has been happening since I was little.  My parents took me to a psychologist when I was little but then stopped, since then they have maintained that  I need to just "get over it".  It doesn't happen all the time but when it does it can be very intense.  

I also had a stroke about a month and a half ago, doctors still haven't determined why I had a few MRI's a few days ago. 

It is the combination of these things and chronic unhappiness that has made me concerned, I am seriously considering asking a professional for some help but any advice given here would be appreciated, thank you.
