Work at a maintenance shop, offer to work for free if you're young and have no skills (some will detest this but why should you be paid if you have nothing to immediately offer?)
You don't have nothing to offer, you have a licence that cost you 100k+, you have life experience, you are providing your labour to someone else so they make a profit and you need to put food on your table and roof over your head.
You are a commercial pilot. Part of being a professional is getting paid for your work. Do not under cut others or you are as bad as the back stabbers Flying Bear spoke about.
