i understand what its like, i've been stuck at home on benefits myself for years, it can get very depressing.
please dont feel guilty about it though. feeling guilty doesn't make things any better, it just makes things worse and lowers your self esteem which makes it even harder to go out. remember that people in jobs often claim tax credits and tax allowances, and that can add up to more than the amount you get on benefits! so they're getting even more back off the government than you.
and just look at what the government do spend taxes on, they waste billions on wars!
so try not to feel guilty, though i know its hard because it can often feel like you're of no use to the world, thats how i get sometimes
can you get any sort of support to help you get out the house? thats helped me a lot. if you could go out or had help to go out, what sort of thing would you like to do?
