Self-Injury Support Group
Whether you or someone you know or love struggles with self-injury, this is the community to discuss your experience, find support, meet others going through the same, and get advice on how to stop. Working together, we can help find alternative coping skills to reduce the urge to self-harm.
Looking at all the issues you're dealing with, i'm not surprised things get on top of you and you feel the way you do. Perhaps try to deal with one small thing at a time to give yourself something to focus on - with help of course. I wish you the best of luck.
Otherwise, I think tatty had a good suggestion. When I was in college, weight lifting was a great way for me to blow off steam! Have you tried punching pillows? I hear that helps too.
