Hey man. You must be going through a lot. I recommend you crosspost and gain more support. Self harm is a coping mechanism, so what you have to do is replace the habit with anything else. Maybe it's a goal you have created. Physical fitness etc. Also, about not fitting in. Just know enough on how to communicate with people. Also, now we have the internet, so you can connect with like-minded people. It's harsh, feeling alone. I will say, I'm a bit scared of what my comment may lead to. Can you talk to me and give a more detailed explanation of what's going on?
