I lost something of my friends and he wants 200 dollars for it I've already told him to wait. So I need the money this week I promised. But I hada pay my phone bill now I'm broke. I don't really have something to sell, or anyone to sell to. I don't get paid till 2 more weeks form my job. Is there anything I could doo?

You can go out and get another job, many people have two jobs... or do without something to pay the amount owed.
