Hey. I'm sorry. And I know what you're going through - I spent a year barely at school at all.
Don't end your life. It's hard to feel sick all the time, but there's so much else to appreciate in it...
I'm no expert, but what's helped me - I will go outside a bit at a time, just staying near the house, until I'm comfortable, and then take it a bit farther each time. Once you've gotten used to it, you can try interacting again.
It's hard. I know. But you're strong. Tell yourself that.
