Quit job > Play poker, EZ!
Seriously though, everyones gotta deal with RL shit so your not alone, i have like loads on at the min and if pokers gotta take a back seat then so be it, chances are this will, at most, become a little extra earner that i can pay the rent with every now and then, i will probs never be a pro poker player so why sacrifice RL stuff.
The number one thing that helps me is playing cash games, that way if i have a spare hour/half hour then i can sit down multi-table a bit and leave when something else comes up or i feel the working day was maybe a bit too hard and im not playing well b/c of it.
If you play MTT's then dont bother imo, they take far too long and the variance is brutal, which doesnt lend well to a tired/stressed out from work mind. If you play SNG's then learn to multi-table and play 10+ at a time, that way you only need to find an hour each day and you can get in 300 per month which is respectable.... i think!
