Breakups

So my girlfriend and I broke up and its completely done. And i feel so empty/angry/hurt and i honestly dont know how to deal with it. i've been through breakups before but this is nothing like those times. i literally cant get out of bed, and my concentration for my classes just went completely out of the window. I want to cry but i cant. i want to eat but i cant without almost throwing up. i just want the pain to go away. any suggestions?
