Find a work and wait for your salary. $50 is not that much better move on and start doing things to make you earned again the money.
Money is not a thing that can be recovered again once you lose it. So work for it. After earnings again $50 or more, up to you if you want to play gambling again. But remember that once you play gambling again, Im seeing you will asked again the same question. Goodluck mate.
This is on point. Go look for a job to regain your loss. Remember that in Gambling we are all losers, If you go after your loss their's a chance that you could lose twice, thrice or more. Don't be so desperate to regain your losses, since it will result in something that beyond your control. Plus, don't gamble with the money you can't afford to lose. Why? This would give you a hard time to recover not only financially but mentally. A simple advice for you, Cut your ties to Gambling. As I can see you will be a problem gambler and Gambling will control you. But if you decided to continue, then do your very best to control yourself. (I hope that I'm wrong)
