How do you cope?

How am I supposed to cope when my emotions feel too big? It’s like there’s a hole in my chest and I can’t make it go away. I feel like everyone hates me and idk how to make that feeling go away. Like even my own family is sick of me and I have absolutely nobody else to go to. this is so embarrassing, but im in the middle of an episode and I don’t know how to make it stop.
