26 female, diagnosed BPD &amp; PTSD here. It's about my self - harm. I was cutting when i was younger and got many scars. After years of wearing long sleeves in summers i turned 18 and got them covered. Its a huge process, is painful and expensive, and i didnt want to go through it again. i started pinching my skin with my fingernails. I break the skin a tiny bit, just enough to let out a little bit blood.   I have no idea how i came up with this, or when i "started" doing it.  year after year i kept doing this, and am still doing it. I mentioned it twice to my therapist and he said it's not an urgent matter, even though he's convinced that this is a symptom. I'm going through a stressful phase, moving and making changes in my life and as my stress levels rise i panic and self harm. I don't need anything sharp to do this, so i can't just put  tools away and be done with it. My upper arms are covered with hundreds of tiny scars. I feel that my skin is getting thinner and slowly becoming a huge scar. When people ask me what happened to my arms i tell them its a skin disorder.  Recently i started doing this with my legs, chest area, private area, neck and sometimes face. I literally sit for hours and pick my skin. I remember doing it for 4 hours once, i was home alone. My whole arm was swollen and red and hurt like hell but i couldn't bring myself to stop. When I'm doing it i almost feel like time isn't passing, like I'm doing something so good i won't ever be able to stop. This kinda worries me and my next app is in a month. I'd like to see how you guys think about it &amp; any advices?
