<human>: Give me the gist of the text in a nutshell

Hi guys,

My girlfriend went to live in a city 45 minutes away to go to university this year. As a result she's been more and more distant as her responsibilities have been increasing. She also joined a sorority and starting recent drinking and partying some more.

I expected a lot of these changes and thought I was mature enough to accept them and the changes to her personality she was likely to have. She is young after all and I couldn't expect her to be the same person I started dating two and a half years ago. However, some of it still feels like a betrayal because of how she used to tell me alcohol was boring to her.

But lately I've been feeling very uneasy. And I've been acting very needy as a result. I know one of her new friends suggested she break up with me and since I've told her how I feel, the communication has not improved. 

I know I can definitely be over analysing things, I suffer from mild depression and it's always been worse in winter months. But I'd like to know what you guys think, should I be looking at this a different way? And what do you suggest I do?

I'm also not naive about my chances, I know that first year students rarely want to stick with the guy they dated in high school. But I'd love for her to do this in our case.

Thanks for listening, just writing this out makes me feel slightly better for some reason.
<bot>: My girlfriend is becoming more distant, apparently due to increased time constraints. This is making me freak out and I don't know if it's justified or what to do about it.
