Alright, I'm looking for a bit of advice.

My girlfriend has been really stressed these past couple weeks because of her job (she's always on call). I do what I can to help relieve it outside of work (cook meals, try to plan fun things, etc.) but for the past bit, she's been entirely zapped of energy and all that fun stuff that comes with stress and working oodles of overtime. As a result, I think we're growing apart a bit (or at the least, she's a fair bit less passionate - which is understandable because of the whole no energy thing)

What can I do, outside of suggesting a career change, that can help this? I guess I'm looking for good stress relief techniques as well as things that can "rekindle" a relationship, if you will.
