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

Hey all. We moved in together relatively quickly (after a year) and are learning now that it's not working with our living situation. Her depression/anxiety has been on/off for the last 6 months, is causing an incredible amount of irrational irritability for her and spilling onto me which in turn causes her an incredible amount of guilt on her mood upswings meaning more depression. 

I love this girl and she loves me. A few weeks ago she confessed (in a rare state of being drunk) that she thinks that I'm going to leave her eventually because her condition is so very difficult to deal with. I'm bearing a lot of guilt as well because I think I would be happier without having to deal with it - at least in the short-term. A time machine that would bring back the girl of our first year together... that would be magical, but probably naive. I see glimpses of that girl but it's a struggle. 

It's a complex situation where now she's wanting to move out to find herself again and focus on her recovery while still continuing to see me. I'm stuck in a state of cognitive dissonance. I'm generally an extremely upbeat happy person and this situation is grinding me down. But I don't want to abandon her and a possibly happy future. Has anyone been through something like this? Is there hope, or am I delusional?
<bot>: girlfriend is battling depression/anxiety for a long while now, we love each other, it's bringing me down and making me demotivated, is there hope?
