I have enough money right now until my husband's benefits can be accessed at age 60.

It's extremely tight, and I have to stay within the budget I'm allotted.
And of course, if something unexpected happens, that could blow everything out of the water.
However, I have a few hundred dollars over and I'm seriously thinking of taking some kind of short vacation somewhere warm, but then I worry should I really spend that money?
The future is not exactly certain for me, and I'm always extremely cautious about everything.
