I've been dealing with suicidal thoughts for a while now, but recently something new has popped up. I have this weird feeling in my hand that feels like I want to take a knife and stab myself. I'm not sure how to get rid of these feelings. I tried techniques my parents and therapist have taught me, like remembering what I'm grateful for and being compassionate towards those kinds of thoughts, but it feels like this feeling comes as a compulsion rather than from any sort of thought. I have plenty of reasons to not act on them and I remind myself of them, but the feeling still won't go away. How can I deal with it?
