Spaz hit the nail on the head. When I was in therapy in the Navy, my therapist told me that many people in emotional pain find relief from SI because of the chemicals released from the body... instant high. Instant relief. That's why it's addicting. Many like me let this behavior get out of hand... and many like me fight the urge to SI every day. Please talk to the doc soon to help you with this. There is a better way and I used to know it. You can find it too. Thoughts, prayers, and hugs to you if wanted.
