Hello, Jack.
I wanted to talk about those suicidal thoughts that are atormenting you...
It's something that I've passed through... The best thing I could recommend you is that you should go find help... Maybe you could tell a close friend o family member... Or even consult a psychologist. I know it isn't easy, and i'm not going to say "Your skin isn't paper, don't cut it" because it doesn't help at all... I just wanted to say that life isn't simple... A lot of bad situations are going to happen... But the important thing is that I believe in you. A lot of people does. So don't give up. Because you matter.
Hope this can help somehow (And sorry if my english is bad, it's my second language)
