Urge to cut myself, PLEASE HELP?

First of all, I'm really sorry about your brother. Try not to think about how your brother felt before his passing, he's in a better place now, he's happy, and the last thing he'd want you to do is cut yourself, so don't do that. Don't give up, don't break down, sooner than it seems life turns around. Just be strong, even if it all goes wrong. When you're standing in the dark, still believe that someone's watching over you, and that someone is your brother. God bless.
