I definitely get the whole "where does my workout fit into my crazy life" insanity. Don't stress - just find time whenever you can, and remember that it adds up - you don't have to do an hour long session, you can just do a few minutes here and there throughout the day. You might even let your kids get in on it... "Mommy, why are you on the floor?" "I'm doing push-ups, sweetheart." One time I broke out a set of ten in between classes at one of my schools, and the kids all thought it was really funny and started counting for me. Then... haha, they all got a bit intimidated when I got up to "seven... eight... nine! teacher, nine! OH, TEACHER, TEN!" The boys even got down to do some with me.
I know this isn't what you want to hear, but seriously, don't stress, don't despair, it'll happen.
As far as your diet goes, still not seeing a lot of fats in there (nuts? animal fats like butter/bacon?). But if you're getting full on one plate instead of seconds or thirds, that's already a step forward since you're cutting your calories in half or better. If you're in this for the long haul, the slower the weight-loss takes, the longer it will last (and the longer the pounds will stay off).
Icarian is right, as well - starting weight and total goal make a ton of difference, as does body comp and height/age. It's a distinct possibility that you are already losing fat and gaining muscle just from your appetite change, so allow for that as well and get a body comp when you can.
If you want to reach the end of the trail, first you must find the beginning.
If you want to be strong enough to walk the trail, trust your feet.
If you want to go fast, go alone - if you want to go far, go together.
