Take a deep breath, don't worry about the past, and move forward. Not tomorrow, or Monday - but now.
The one thing that I would point out is that perhaps you're trying too much. When I read your opening sentence I really did think that perhaps you're almost setting yourself up to fail. Then I read about the house, but still...
So i was doing SOOO well, I was down 13 pounds in about 3 weeks, exercising 2 or more times a day. and drinking water like crazy.
More than 4 pounds a week is a pretty fast loss. Exercising 2 or more times a day is a lot. I walk 5 mornings a week (with a little jogging) and lift weights 3 times a week. That means that two days I exercise twice a day, but the other days only once. As well, I take one day as a rest day. It's important to give your body a little time to recover. (Although to be fair I usually end up doing stupid things like big projects - canning, big garden projects - on my rest day.)
It's wonderful to have that enthusiasm when you start trying to lose weight. However, that intensity is almost impossible to keep up. You'll find yourself one week wondering why you're killing yourself and maybe not losing weight that week. For me, in the past, this has often led to the 'forget about it' mentality.
So, unless those workouts are really short, stick to one (occasionally two) per day. Getting the food under control is probably more important. Although, make sure you eat enough to fuel your body. It's sounds silly, but not eating enough only works for a little while. Oh, and serious house cleaning can count as a workout you know. I'd be willing to bet you burn more calories cleaning for three hours than working out for one and sitting down for two hours. So, don't feel guilty for skipping a workout if you're ripping the house apart.
As to homes being a time and money pit... can't help you with that. It sometimes gets better (fingers crossed as I type that as my own has been good for a while).
