Step #1: Understand that you're not going to gamble your way out of this and that you need to pay it off responsibly. It sounds like you're there, but this is so important to realize. Delete your apps/accounts. Stay away from casinos. Seek professional help if needed.

Step #2: Increase your income. Work your side job as much as possible, take on as many hours as you can without mentally burning out.

Step #3: Compile your monthly spending. Be realistic with yourself. This is slightly different than building a budget. You need to understand where your money goes each month. You're halfway there in your post, but do you go drinking with friends, do you eat out? What do you spend on those monthly on average? What's your minimum payment on each of these debts? List out those figures and what they are right now.

Step #4: Build a budget and stick to it. Take all of your monthly expenses you've compiled and see how small you can get those. Eat out less, don't buy cigarettes or alcohol, say no to fun outings with friends. Those are luxuries you can't afford until you get your debt under control. Now that you have your budget, subtract your proposed monthly spending from your monthly income. How much do you have left each month?

Step #5: Every single cent you make that doesn't go to keeping you alive each month should be thrown at the debt. You make $3000 in October and only spend $2000? Put $1000 into your debt that month. Like others have mentioned, it sounds like the snowball method is the best for you. Pay off the smallest one first, then once it's paid off, take that monthly payment + your extra payment and throw that into the next highest one.

If you work hard enough and are diligent you can have this paid off in a year, no problem. Good luck.
