I hope you get the help you need.
I am sorry you are feeling that way.
a crisis line may help, they've helped me, it looks like you live in the US: http://suicidehotlines.com
Your campus or school may also have warm lines available. Do you have a place or person you could be with to help you be safer?
I do hope also that you will call to talk with someone that can be with you in person or on the phone through this. A hotline like the one above is a great resource, please don't hesitate to use it. Please be safe and if there is anyone you can be with now until these feelings ease up please do.
Here's also an online chat resource: https://www.imalive.org/
