What to do

For you all that do not know my story, I had surgery 28 of November in Mexico.
I am self pay patient and payed 4500 dlls every day as some of you might know I have been working my ass to the bone.
Before the surgery I was only able to walk about 15 min, I am know able to walk around 45 min.
I still get sweaty and feel tired but not after just 15 min I can actually go the whole 45 and then I am done.
But the problem is that every day I walk just that five steps more and that is not the problem it is raining so bad that I just am not going to be able to go walk around.
I feel that if this rain does not stop soon I will be in big problems.
I will get lazy and not be able to force my self that five steps more everyday.WHAT TO DO?
Does any body feel this way?
I hope that the rain will stop soon, but lets face it we are just getting into winter this SUCKS.
Does anybody have any ideas what I can do for exercise?
I just work so hard everyday for my kids to be a better person.
Some advice please help.
