You can speak and type in coherent English. If you can get up in the morning, bathe, and show up, you can get a job of sorts. Maybe not a killer job, but a job should be easy as shit to find, especially this time of year. Show that you're willing to bust your ass and you'll be one of the guys that they hang onto when it's time to make the post-holiday cuts.
If you can slide by taking advantage of whatever benefits and freebies you can score for a while, you can save money and get a place, even if it's a roommate situation (seriously, even though it's petty if you want to get a hard look from the estranged wife moving in as the roommate of a completely platonic female will score you points). Regardless of whether you get back together, having a job and having a place will move you along farther than you can imagine you're capable of moving right now.
At one point, I was the youngest low-level executive in his early twenties at a major national bank, raking in a healthy six-figure income and having my name on title to two houses, with five cars and an RV in the driveway and four motorcycles in the garage. At another I was a laid-off divorcee learning the ropes in the construction trade as an unskilled laborer working under guys a lot younger than me who were collecting more than double the $11 an hour I was taking home...I'm still not back on the high horse I once rode, but by committing to putting my dues in every day even after crushing failure I've managed to find a wonderful wife, spectacular stepdaughter, and enough reason to get up every morning and fight to make tomorrow a little better. I wish you the same.
