what are you taking time off for?
* A very needed break? -> give yourself a few days to feel the exhaustion.
* Time to lose more weight? -> don't overdo it. Think up something you can keep doing, also when working. Slow and steady is better than a crash course of barely eating and lots of exercise.
* Time to think about schooling? -> what is it you want?
For exercise, can you use a bicycle where you live? With bags attached to the rear, you could then try to do all your things within a 5 mile range on bicycle. In a month or so you could enhance the range. A 10 mile range would be peanuts. It light on your body, the bike carries the weightbut you do train your body well. And it's a habit that you can just keep up.
But, it needs to be safe to bike, for it to work.
Swimming is a good option too. Small risk of injury. Big effort for the body.
And then there are exercises on line. Find some with some fun in it.
With all things in exercise and food, don't go crazy. Find a way you can keep up with. Make healthy habits. They last longer than a diet.
(In stress, you may still lose them, but hey, new habits probably can be found. I'm going for it.)
