it' okay to feel the way you're feeling. It's also very important to let it all out. Feel free to be as open about it as possible, because in the end, no one will know...
Life can be hard and you feel like you don't belong there, that you're different and that you just don't fit in... but hear me out. You're one of a kind, you're special. You deserve all teh good from the world, so don't think otherwise. It's time to start living, of course by not hurting others. It's just a mad cycle if you make others feel bad... it'll eventually all come back. So think wisely before you act.
You are you, and you are allowed to live, so enjoy every second you have and be a better version of yourself.
Good luck!
