Small places are sometimes good places to look for work. Small retail stores, boutiques, neighborhood print shops, dry cleaners, veterinarians, pet stores, used car dealers, rec or senior centers, bank or credit unions, (branch, not main bank) espresso joints, property management agencies, you get the idea.
As for parents charging rent, you may have just outworn your welcome. Especially if you're not working and your parents (both) are. They shouldn't have to take out the garbage, wash dishes, empty the catbox, dust, vacuum, shovel snow, mow the lawn, trim the bushes, etc. I know if I worked full time and came home to a bunch of housework that needed doing while there was a non-contributing adult living there, I would be pissed.
So even if you can't find a job, I'm sure you can find work --around the house. If you can show an "attitude of gratitude" instead of entitlement...
Just think of every household task or chore as a "thank you note" to the providers of your quarters.
