Care giving, help in understanding what to do.?

Think is i became unemployed a couple of months ago. i know that's no big news. but a couple of weeks ago i stated helping a relative. who is house bound. and needs help all day long. i promise it's hard work. but that's ok. thing is i've been told that if the job centre find out i could lose the job seekers allowance.

If so is there any other allowance that i could claim because the allowance i get now is all i claim i don't claim for anything else. so it's all the money i have. and although i can live on very little i need something, and cannot expect the person i'm looking after to pay me, as they don't have much themselves. any ideas would be much appreciated because i'm new to all this sort of thing.
