is making time even possible?

from the beginning of our relationship, i have always been the health nut: watching what i eat, exercising (although sometimes infrequent). well the tables have turned. between work, running the house, taking care of ella, jerm, and the dogs, at the end of the day or at the beginning of the day for that matter, i am utterly exhausted. in may, jerm made a huge decision to change his lifestyle to a more healthy one. the person whose veins ran coke, now only drinks water or gaterade. the person i would beg to eat more healthy is now eating good things. and on top of that he has been exercising. i am soooo proud of him!! we bought an elliptical in june. in the last 5 months jerm has used it at least 4-5 times a week on average; i have used it a total of twice. how terrible! great for jerm but terrible for me. i have got to get some time, energy, and motivation to get into shape. the stress at work has caused my appetite to decrease and my metabolism to increase so i have lost the remainder of the baby weight. which is not a healthy way to do it but it was unintentional. but i know that i need to get back into exercising; it's just the legistics. i get up around 5:15am, at work by 7am, off work at 4:30pm, pick up ella, home around 5:15/5:30pm, ella eats at 6pm, play with ella, give her a bath, ella in bed between 7:30/8:00, get her bag/food/clothes ready and set out for next day, usually need to cook and/or clean up from dinner, maybe work in some laundry, by then it's around 9 and all i can think about is sleep. i am asleep within 2 minutes of my head hitting the pillow. only to wake up and do it all over again the next day. i am not complaining; maybe i am justifying but legistically exercising does not fit into my daily routine right now. i would have to deprive myself of sleep to get up earlier or go to bed later and work out then. i don't think so. now i do walk alot at work (our office is huge), i take the stairs in the parking garage every day, but its not aerobic exercise like i know i need. so anyway, i know i need to figure something out but there are only so many hours in the day.
