<human>: Provide a brief overview of the text.

Started seeing my now girlfriend in the summer, august (UK) we are from totally different backgrounds, but both passionate about horses.
Summer ended, I'm back at university, she is working. Things continued at a slower pace but the excitement of seeing each other was pretty awesome.. I would come back from uni most weekends and we would do all the "normal couple stuff"
I've met her family and we have told each other we love each other quite a long time ago.. We did have a pretty amazing thing going on.
I left the country (organised well before we met - I did tell her early on and we both thought it would be fine.. ((we're stronger than this etc))
So as I see it, I'm slowly drifting out of her life little by little. She has told me how she has been hurt so many times and never felt like this with anyone. I am passionately in love with this girl/woman.
She told me she needs space and tells me she has depression..
I read up about depression r/depression is actually really handy.
She tells me its been over a month now but she has just been hiding it.. ( i left on the 16th of dec, so it started about 2-3 weeks beforehand.
I'm lost, i feel inadequate, i think about her all the time, I'm angry, an then really sad.. I then tell myself stupid shit like "she is acting" "attention seeking" ( i won't lie she was always a bit needy.. now i feel like a total dickhead writing this as its only now becoming clear. This is my first proper relationship. I need advice.
I'll be back in the UK in about 12 days, we have been radio silent (no text or phoning) for about 48 hours, which is a first.
but she wished me happy christmas and send me two snapchats (i haven't opened them) I'm trying really hard to just let her be alone ever since she asked for space.
<bot>: 6 month relationship steadily becoming long distance as we drift apart. GF is suffering depression of some sort, I'm not in the country but will return soon. (12 days) I love her, but she wants space.
