I'm so depressed

I can't smile anymore at all and I can't stop crying. I'm really lonely and I'm stuck in a situation I just want to get out of but there's no way out and it's crushing me.
I love my boyfriend, so much... I'd do anything for him, I think the world of him and he makes me unbelievably happy when we're together. But, it's a long distance relationship most of the time because he's at university 300 miles away in a different country! It's killing me... it hurt to start with but no it's so much worse... I REALLY love him and I'm so unhappy without him. I know I have two options: 1. Keep the relationship going and just hang on another two yeas for the 'chance!' I may see a lot more of him or 2. Break up with him
But I can't... I can't break up with him because I love him so much, but the hurt is killing me, I cry every day, I'm so lonely and I hate the fact that when he's home or when I'm with him I'm happy and the problems I have are easier to deal with.
I just HATE, really hate that I'm hurting loads either way. I'm struggling so much right now and noone understands. I feel so alone.
I can guess that some of you may say "leave him and yes you'll hurt but in time you will get over him"... but I won't. I know that because I love him so much and I don't even have any friends to help me through it.
Others will say "but if you love him so much you'll wait for him"... I want to wait for him. I just hurt too much, and it's physical hurt every day.
I'm a mess... this is just one problem to throw on top of all the other problems that have made me depressed in the first place.
I don't even know what I expect to get out of posting this, I don't know
Sorry guys if anyone read all that,
Molly
