<human>: we have been together since my 3rd year of college. She is truely the light of my life, I don't have many friends and she's the only person, besides one guy friend who I see occasionally, that I spend time with. 

We started dating when I was in college, which wAs good. School work distracted from my problem. But once out of school my depression got a real hold on me. I ended up basically ignoring our relationship, I would turn away from going out with my gf and her friends, and I even cancelled going out of town with her to her best friends birthday(she went without me).   Our relationship suffered greatly, the two of us would see eachother maybe once or twice a week, and I would never make the best of our time together. She felt my attention was always elsewhere, when I was actually jut trying to stay sane and not tell her how badly I was hurting. 

I always thought if she really knew the depth of my depression she would run away.   By sadly, after 3 amazing years of her by my side, she tells me she has become emotionally exhausted. And is just tired of trying when it felt like I wasn't reciprocating.    

I'm in a mad panic, I don't want to lose her. I don't want to let my depression get in the wAy anymore.  I've got a prescription for some antidepressants and I have started working out again.    I'm also getting back into my hobbies.   

I'm worried that by his point it may just be too late.  she may just be ready to move on; but another part of me worries she has found someone from her social circle.

Can you give me a shortened version of the text?
