SUBREDDIT: r/relationship_advice
TITLE: Break up advice...
POST: Well, I won't explain how the relationship was or what happened since I don't want to go back or need to fix something, she's the love of my life but it's over. But here's the thing I need help with:

* I live far from my family and best friends as I'm living in another country.
* I do have friends here, but I still don't feel I can rely, sentimentaly, on them, they are great, but I just can't right now.
* I can't talk to my ex or even use facebook because it hurts even worse than that time I went to the hospital due to incredible pain.
* I'm a university student and I have a lot of pressure from finals.

Basically I'm breaking down, I don't know what to do, I "know" how to deal with this and the depression but... it's fucking surreal, I've been through worse life situations but this feels way way harder...

As I said, I "know" what to do but it just keeps hurting like a bitch. I need redditor's advice out of experience, not from a book or from a talkshow.
TL;DR: 
How do you move on after the love of your life left you, you can't and don't want to go back, you have no one to rely on, and you're deep in stress?
