Welcome to PC. I am so sorry your parents are unsupportive of you. I know how hard it can be to resist to SI. There are some suggestions of things to do when you feel the urge to harm yourself in the self injury forum. You may want to read them and see if anything works for you. Is there anyone in your life that can help you work through all that you are feeling? Sometimes it is so hard to do on your own.
I am glad that you found us.
