First you should decide, then change things and work on your way to achieve your decided goal. It's the only way to get things done. There is no shortcut. But give yourself a pat on the head for realizing this sooner than later. Learn from your mistakes. You make it sound like you know your gift, your talent. Use it and don't be afraid to make mistakes. Live. You only got one life after all. But also, don't forget to show kindness to those who'd stuck by you when things were tough. Show appreciation to your parents.

If what you want to achieve is something you've never had, then you must be prepared to do something you've never done. I've read a quote like this somewhere.

Everyone struggles with this don't be ashamed your young learn from your mistakes. Take a coarse to learn budgeting and money management. I hope they had a coarse in highschool that teaches young people how to be financially responsible. Good luck

Stop the escorts and drink less, how many hours do you work usually? Calculate how much you earn and find a bank that has a no touch savings, use that as piggy bank, but make sure you can have access to it, sooo when you need or ready to use some of it you can.
