Hello again Mercy,
If you are having suicidal thoughts, please consider getting help. I'm glad you said you don't think you'll act on those thoughts. 1-800-SUICIDE (1-800-784-2433) is a hotline you can call with people to talk to.
I've heard that holding a piece of ice to the place you want to self injure can relieve the urge to hurt yourself.
Please take good care of yourself.
Peace
