cvt myself with a glass shard last night, tempted to do it again. what do i do

I feel like school just made life worse and for what bullies and to become rich does it matter that much I mean me and my family are going broke paying for me and my sisters bills to go to a Christian school like why 2,000 every month and for what we drive a 1 hour to school every day I was taken away from all my friends I know it's not a big deal but it is to me idk man

I despise my school friends. They treat me horribly, especially after I announced I'm moving cross country. I'm miserable and I can't wait to leave them.
