What do you do?

As of recent my life has sort of crumbled down around me. First I’ve got depression which doesn’t help me at all. Then my girlfriend of 3 years breaks up with me. I could go in on how we were meant for each other and we had so much we were going to do together. At this point it’s meaningless. I’m a shy person I don’t really talk to people and I have no one to help me through difficult times. I just feel like there’s nothing good anymore. Any advice on what do next
