I had a really hard time with all of this in high school too. Instead of suffer I spoke with my teachers and got special permission to do alternate assignments or one-on-one presentations instead. It made my school experience immeasurably better. Your friends seem like shitty friends, so for your sake I'm glad you're in your last year of high school so you can meet kinder, more understanding people soon. I promise it gets better! Teenage me couldn't even begin to imagine the life I have as a 30something but here I am. Maybe therapy would be a good start for you though.
