Earlier this year I started again after 6 months, I know how tough it is when you've stopped for so long. You can stop again, it will be hard, but nowhere near impossible.

As far as the situation with your friends, try to think of it this way. With your old friends you can still talk to/text/hang out with them outside school, and you have an opportunity to make new friends. It's hard talking to people about things like SI especially for the first time, but you dont need to tell them, and you definitely don't need to if they're not really close friends yet anyway.

If you're being bullied you need to tell someone. Especially if it bothers you so much that you SI. No one has the right to bully another person, someone needs to stop this guy.

I hope things go well for you, and PM me if you ever want to talk.
