Please don't hurt yourself. I used to self-harm by cutting and bruising myself, but my family found out and it upset them. I can relate to how tempting it is, but it's dangerous, and you deserve to treat yourself well.
I'm sorry you feel like you have nothing. :hug: Do you have family or friends you can talk to? My family has helped me immensely, and I'm blessed, but I realize that many people don't have it so easy. If there's not really anyone in your life you can confide in, know that there are many caring people here who will listen and help if they can.
Feel better. I'll be thinking about you, and praying if that's all right with you.
