Im 15, living in a foster home and im in psychotherapy due to my intense phobia of mushrooms and trauma. This is my 3rd year. Im already diagnosed with depression and anxiety. I pretty much have all the symptoms of bpd, ive had intense feelings of boredom for a long time, im a people pleaser, like no matter how bad my bestfriend fucks me up i still do anything she asks because they will change and i tend to overlook the negatives and try to see the best, self harm (hitting myself, cutting, scratching) for years now, shit i dont even know what i look like, i always try to change my appearance to look different but then i think i looked better before and the cycle continues. smallest inconveniences either make me really sad or really angry, i dont show my anger or sadness to others though, so if im upset i dont show it. 
Theres just so much , and i feel like it explains a lot. Idk what to do though, i dont know how to tell my doctor because i feel like im attention seeking or that its some teenage phase thing. I
