<human>: Can you give me the gist of the text in a nutshell?

So basically, I feel really really shitty at the moment, my girlfriend is going away and I'm not going to see her for 8 weeks this summer.. the longest we've ever spent apart was just under 4 weeks. 

I plan on spending as much time with her as possible before she goes away but I'm afraid that might not be possible. I'm not gonna see her for 8 weeks and then I'll only see her for 3 days before we need to go back to studying.

I don't really know what the hell to do, last summer she went away aswell, but we barley spoke and didn't even Skype, I (regrettably) ended up kissing another girl but I told her the next day and we broke up soon after for a few weeks.

Is there any advice anyone can give me? How to feel less shit about everything in general, she really is the most important thing in my whole fucking life to me and I'm really scared for this summer.

What do I do? :/
