I remember when I left my FOO at age 18, with my bike, and some few clothes. I did start with a place to go, but soon ended up homeless, and it really wasn't fun. It was doable, but draining.
Could you explain how your family discourages you from working? Do you have any supportive family or friends nearby? Was the bike supposed to be yours or? Riding a bike to work is actually a good idea, depending on how roads are laid out where you are.
It looks like there are general labor listings on craigslist in your area that do not require experience, but if you have some talent or ability, check with these even if they are asking for experience. For example,If you have younger siblings you have been caring for, apply as a manny. (What we call male nannies here, My son and his wife had one at one time.)
Look for a farm or ranch job, if that would suit your talents and/or personality. (These suggestions would possibly give you a place to live, too.)
Advertise yourself for a position wanted, and keep on top of it,with an email address for contact, and try to check email a minimum of once a day. Really try to think of something you could possibly sell or do to get a cheap cell phone.
Now these suggestions are only suggestions. If you like any of them use them, but they are really just to get you started brainstorming for what will suit you. You kinda posted an ad here, so expand on it, bump it up occasionally,sell yourself, and don't forget to advertise in multiple venues.
I'm really curious about why your family is trying to deter you from getting a job. Do you know why?
