You are worthy of love! Absolutely!! Scars or no scars, you should be experiencing all the love and support you need right now. If you're not, that's something that's wrong with the world, not you!
I understand how scary this can be. Please be safe and try to find your inner strength. It's in there. Use that strength to love yourself and know that you are doing what you have to do to get by until you can find a way to get by without cutting. Please take care of your self.
