Hey, I'm gonna skip the "sorry" part because that is just full of shit and I feel like it's a worthless way of showing sympathy. Don't ever think about suicide and I can understand the sense of worthless you had during that fucked up period. Hopefully that moment did not hinder your friendship with her. It's that sick fuck's fault for trying to rape her. Don't you worry brother. Try to calm yourself down, and if possible don't take drugs. Hopefully you're not one of them :(
Sorry if I showed signs of rudeness in my post, i'm not very proficient in my tone of language so I might come of rude. Have a good day and I wish you well in the future
