I really feel for you, man, and I'm sorry for what you're going through.
Stress affects every aspect of your life and it surely will affect the most physically rigorous activities you enjoy doing - i.e., strength training. In my opinion, it is possible to maintain strength gains even by training once or twice a week. If I were in your predicament, I would cut my training down to no more than 3 times a week. Is the stress causing you to lose sleep? Yeah, if that happens you're in a world of recovery problems. Not getting adequate sleep is something I've struggled with.
As far as stepping away from training completely, that might be necessary but I wouldn't recommend it. I'm going through a hell of a stressful time right now. Everything in life isn't the way it should be. But the only outlet I have - the only thing that gets me excited about being alive - is barbell training. I think you should keep going but lower the volume a bit and try to get more rest. I hope you get everything sorted out soon and still have enough money to maintain a good calorie intake.
Good luck.
