I guess I'm self harming now (cutting, deliberate pain ect) and it's due to the fact that my life seems almost worthless. My best friend (I accidently hurt but not sure how) has been ignoring me which has hurt me so much considering how close we were. I genuinely thought that I should just die because I couldn't take anymore of how she was treating me.
So my question is; How can I try to stop cutting or make my life seem better?
As far as making life seem better, it's going to depend what the root cause is. You can try journaling to explore what's making you feel this way yet always include something you're thankful for and something good that happened that you enjoyed that day. Or simply do the latter half, but I honestly believe that unless the root issue is dealt with, there will be little progress with just the latter half. I also suggest looking at yourself in the mirror each morning before you go off to school/work/whatever you're doing that day, and tell yourself aloud that you are beautiful, you deserve to be happy, and you will have a good day.
It's hard when friend start ignoring you out of the blue and don't explain why. It has to be even harder when the friend says, "You hurt me," but won't explain why. Makes me wonder how much the friendship meant to your best friend that she's not trying to talk things out. Have you tried calling her and saying, "I'm sorry I hurt you, and I want to work things out. I've done a lot of thinking over the events of the past few weeks, but I honestly can't figure out what I did. Can you please point it out so I won't do it again?"? If you haven't, I'd try. Make sure your friend knows that you understand if she can't yet talk about it but that you would like her to call you when she can because your friendship means a lot to you.
Best wishes!
