<human>: Summarize the given text in a few sentences.

Okay so, she has only been my girlfriend for 3 months but... I'm not sure how to explain it, it feels like years. Have you ever met someone so suited to you, and so nice that you question their existence? Well... Not quite to that extent but you see what I mean haha. Anyway, this girl is the nicest and most truthful girl I have ever met. Our personalities are so alike, that even on the first date, there were no awkward silences, we always had something to say. And when we didn't, we'd just make awful puns.

Ever since we met, I knew that she was moving to a city called 'Manchester' (an hour train ride from here) to do a 3 year musicianship course. Initially, it didn't really bother me, I thought 'well, if this really goes well, then we can make it work!'. Then there's today, this was going to be the last time seeing her in 2 weeks. I'm so used to seeing her 4/5 times a week and now it's going to be 3/4 times a month. We said our long goodbyes, in the rain, it was guite bliss, actually. Then the moment she went home, everything hit me, and I cried my eyes out for a good hour. Now I'm the kind of person that doesn't cry, I usually can't! But now it's 1am and tears keep building up in my eyes and going away again. I feel trapped, alone, scared and SO ANXIOUS. I'm stuck with "bad butterflies" in my stomach. I'vehad anxiety the past 4 months and it makes it **so much worse**.

Can I have some kind words that'll make me feel better? Maybe some tips? I know that we'll never break up, but my mind automatically switches to thoughts like 'it's over', 'what if?', 'it's not going to work'. Why is my mind doing this?!
<bot>: Met a girl, she's perfect, she moved to another city (an hour away by train) to study, my brain is producing awful thoughts and they're racing, need tips and kind words.
