TITLE: Relationship issues have wiped out my [23M] appetite, I can't eat without vomiting my food back out, please help
POST: I'm planning on breaking up with my girlfriend soon and this entire situation has thrown me into a depressive spiral. 

I have eaten about one meal per day for the past 5 days. My sleep schedule is destroyed and I am only getting 3-4 hours of sleep each night and lying in bed through the afternoon. My stomach is in pain but I am not hungry, I've eaten a few meals with my family just to have to excuse myself to the bathroom because it won't stick. I've also been dry-heaving just thinking about how shitty the reality of the situation has become. This is freaking me out because it's never happened before, I have no history of disordered eating or depression like this. 

I'm going to be going out with friends this weekend and I want to be well enough to have a good time and take my mind off of things. What do I do to begin stomaching food again?
TL;DR: 
shitty breakup about to happen, can't eat, can't sleep, need help being able to eat food without puking it back up.
