I don't know what you do that you hate so much, what transferable skills you have or what else you could do, but... honestly, yes, it could be very bad for you. There's a lot of crap going around (mostly from the government) about job opportunities for older people. Unless you can easily find another job (and if that were true, why haven't you already done so?) and have in demand skills, why would an employer want an older worker, worn out somewhat and who costs more???? (I say that as an older worker too). Then there's the whole, why did you quit a perfectly good job when you haven't got one to go to - that's red flags all around... it screams that you might have been sacked, resigned in disgrace or whatever. It is seldom read as "this person decided to take six months off". Of course, you could tell them the truth about hating your job and just deciding to quit. Assuming they believe it, that labels you as unreliable and likley to walk out on them too.
I'm sorry, I really get how you feel, but plase don't do anything precipitous. You don't have enough money to live on, you don't have a savings pot big enough to even get you through retirement, never mind the next six years, you have liabilities that you must pay for, and adding to the burden of your husband by deciding it should all fall to him could ruin your marriage.
Take some time off sick - you are obviously stressed. Think through your options, speak to your husband, look at the alternative employments available and work the numbers. But a state pension and a small private pension in six years time, with all of your savings long blown on basic living for a short time now, that simply isn't a rational strategy. It might feel good to be free for a month or two, but reality will almost certainly kick in, and you may not get the chance to rewind.
