I've been out of work over a year, have burned through savings, have to support wife and two kids, wife has threatened to leave... so I can empathize with all the stress. Certainly moving the family in to the grandparents is one of my fallback options.
Not drinking has helped me deal with the stress. But also, while losing a job is a blow to the ego, and moving back to the parents is a blow to the ego, my alcoholism and inability to get sober were much larger blows to the ego.
Also, to me part of recovery is being better at accepting help from others (as I couldn't get sober by myself). I'm grateful for the support given to me by others in AA. I'm also grateful for the support (especially financial support) given to me by my parents.
So maybe you may want to rethink how you perceive your situation. Times are tough, but your parents are there for you, you're doing what you can on the job front and you've managed to stay sober. There are no quick fixes, but you have a lot going for you.
