Hi singularapathy. Sorry to hear about your situation.
First up: I haven't read the whole thread, just the first page. Sorry, too long. I just wanted to offer a counterpoint to jim_doki:
jim_doki said:
as far as im concerned i see her as a sinking ship. i guess what im saying is im not sure how much help you can be at this point, and maybe its time to think about you for a change. I'm not saying this to be heartless, i've actually lived through something very similar. Yes, she needs your support, and yes she needs help, but if she's not gonna take it there's not a lot you can do besides watch the carnage unfold. I wouldn't want to go through that again.
I just want to say "every situation is different" - a cautious vote for optimism and hope. I'm in a somewhat similar relationship, see, and I don't think you necessarily have to cut and run. On the other hand, it might be the only option; but it depends on so many things.
My girlfriend has serious depression (which seems to stem from neglect and emotional abuse as a child, rather than purely from unbalanced body chemistry), and while it's really bad on bad days it doesn't sound as unrelenting as your girlfriend's condition: she has days where she says she feels nothing, that I'm not helping her at all and that she thinks she'd be better off alone, but those days are rare. Maybe jim_doki has been in a worse relationship, closer to your situation, and knows better. However, if your girlfriend's mood is cyclical as you say, you should definitely stick it out until things get better and
talk to her then.
In the meantime:
* Keep a sense of humour. Even if it's gallows humour.
* Don't take things to heart. If she gets pissed off at you, even if it's for something you
did do, remember that you didn't really cause her unhappiness and the fight itself is a passing thing.
* Take care of her, but don't be too protective. Give both her and you space. Don't let her get dependent on you, so she panics when you're not there. Even if she's miserable, she should feel competent to take care of herself.
The single most important thing for me is this: people remember good times when they feel good and bad times when they feel bad. It's just like how you can lose something while drunk and forget where you put it until you get drunk again, when you suddenly remember - it's all about how your memory uses your mental state as a cue. So when you feel like shit, you look back on the year and all you can remember is misery. Then when you feel ok, your previous worries seem trivial. Remind her of this, too - it might help.
