On bed rest, feeling worthless and helpless... what can I do?

I am 38 weeks pregnant, and have been placed on bed rest for the duration due to pregnancy induce hypertension (NOT preeclampsia, or at least not yet anyway). I have no protein in urine or any other symptoms of pre-e, just high BP readings. My BP is fine as long as I am resting in bed, but if I get up and move around at all, even to shower or fix a quick meal for my 7 year old, BP skyrockets and I become dizzy and nauseated. My husband is a departmental manager with 70 employees and a pretty demanding work load, so he can't be here to help much, and we can't afford to hire a helper. I feel completely worthless as a wife and mom when I can't cook our meals, clean our home, do laundry, or anything really. I feel lost, ashamed and helpless, and I don't know what to do. Would my doctor be willing to induce labor a little earlier than what they consider "term" if it is due to the emotional damage this is causing me? I really don't know how much more I can take... it's killing my self esteem and making me severely depressed.
