Maybe your worker can give you some budgeting help. I tried to list out some possible expenses in my posts, but you did not really respond to them, except for vaguely agreeing with the car stuff.

Do you use cash or a debit/credit card or checks? The last two give you a record of where your money went. For cash, some people find it helpful to keep a little notebook and write down everything they spend. You can try to figure out where you spent money in the last week or month, or just keep track going forward.
