Get yourself into a classroom again. It doesn't have to be an ambitious course. It's a familiar structure and you've been out of it long enough that it'll seem refreshing. While you do that go hit the gym if you aren't, yet. (Or if you want to do it on a budget, get a set of resistance bands.) Set lots of simple goals with structure and regularity. Journal your progress. This will get you back into the thick of things without the nasty obligations of the workplace - by the holidays you might have a good plan together.
