Help I need advice to get over her I'm really depressed? (please read all Or at least most)?

Well, it sounds like she's super, super upset at you. But it also sounds like you're beating yourself up a lot. I think the only thing that you can do is write her a long fb message and be way more honest that you're comfortable with. Tell her all about the crying thing, and how you feel like you'd do anything to get her back. Spill EVERYTHING. And say that you love her. When you admit more than people usually do, it shows sincerity. If it doesn't work, then you did all you could. After you send it, don't act weird around her at school. Just act like you did before the fight. I've done this before and it always had amazing results. You just have to pour your heart into it and she might just forgive you. But if she doesn't, don't worry about it. The best things happen when you're really down and you don't expect it. I really hope things work out okay for you =]
