Do you think I should just forget about looking for work?

Continued from the question and wait 2 more years to collect my social security or should I keep trying? Right now I am a caregiver for two granddaughters and my wife. It is pretty much a full time job that I am doing here in the home front. But at times I get bored and feel like getting out there and work but that would be a hardship on them being that they depend on me for just about everything. So what do you all think?
