A.M.
I can relate to your troubles. My husband is very defensive if I even lightly touch the subject of needing more from him, or feeling that I do more than my share without appreciation. The fact is he does do a lot and he too feels much of this hard work goes unappreciated.
I think one good thing is to, by yourself, go about lightening the burdens on you. You don't have to tell him "because of you and the way our household is running, I need this change," you just do it. (After reading the other responses, I want to clarify: It is great that you are communicating with your husband about this. But instead of asking more from him, you could just say "I need some help and I thought of a way we could both be unburdened." Anyway, don't be secretive, just don't be confrontational and remember that he may feel the same way.)
I suggest getting a housekeeper/cleaning lady if you don't already have one. Having these chores taken care of, and living in a neat and clean house, will probably really help your state of mind and other things will feel like they're falling into place, and that you have some control.
Outside of a housekeeper, I'd just try to delegate as much as possible in your life so you can free up some "you time." If you have family nearby, let them do some shopping for you or host you for meals. If anyone offers any kind of help, take it.
And at work, try to delegate. It will force you to be organized and to trust people, and will thus be good in the long run anyway. I certainly can't say I take all my advice, but maybe writing this to you will remind me to do so. Good luck.
(P.S. It's great that you enjoy your job! So many people don't seem to. I'm a research scientist and I love that, and I often feel like all the other Moms on Mamasource are coming from a different place on the balancing-work-and-family issue.)
