I'm in the US and get a fixed income for disability, but it is just enough to barely get by. No extras like new clothes or a dinner out, etc. It is an awful struggle as I tend to not manage my money too well. I dont' exactly make the best decisions when I am in a manic phase. I am also an easy target for others looking for a handout, a cigarette, food, money etc. Learning to say no finally but now keeping to a budget.
I just make a list of my bills and pay them on the day I get my check and then whatever is leftover is what I live on. Usually doesn't work too well as I am penniless by the 3rd week and then have a week where I am borrowing money. Then I start in the hole when my next check comes. And of course no one ever pays me back.
