i cant stop crying

This is what you do. You find anyone and everyone who cares about you, and keep them as close as possible. Don't push them away, let them slowly change you until you can stand on your own again. Take their advice and always come to them with your problems.

I had the same problem. I eventually realized i was turning into a stone wall, and started confiding in people, and i slowly changed into someone who isn't so dead inside uwu

Don't ever commit suicide. Not only is it a permanant solution to a temporary problem, but it also permanantly damages the people around that person.
