Hmm...I'm not sure. I actually think about this often. Even though it's not one of my fears burning to death. I wonder why i SI at all when I hate pain. Like I can't stand getting burned by my hair straightener, but I can stand to burn myself when I'm hurt? like it's so contradictory. I guess one of the reasons could be I feel less pain or almost no pain when I burn myself, but I feel intense pain when someone hurts me. This is a great question you brought up
