I know this thread is old, but I've been gone a long time
I wrote these reasons not to si a long time ago, when I was trying to convince myself I wanted to quit.
I know that many of these reasons are hard to believe or internalize, but I hope this lists helps someone. Take it one day at a time...
It brings as many bad feelings as it chases away
You have hurt enough
Protecting the child inside you, who is already wounded
Self-injury makes relationships with others harder: it isolates you, may make you feel ashamed and/or feel the need to be secretive or push others away
You need to be able to experience your feelings in order to learn to cope effectively, and recover
Feeling worse about yourself after you're past the si incident
You do not need to have cuts or scars to prove it: your pain IS REAL
You do not deserve to be punished
You have a right to your feelings, and you have been denied that right for too long already
Avoiding si can help you learn to feel safe with yourself. You deserve to feel safe
You can rely on your higher power, whatever/whoever that may be to love and protect you. And you will feel that security and safety even more when you are not being self-destructive
Self-injury is a "quick-fix" that really doesn't fix the problem, only distracts from it temporarily
Real healing is possible for you, even though sometimes that is hard to believe
