You need a plan, man. Maybe view it like these get-out-of-debt snowball plans. Pay off the small debt first, then take that extra money and apply it to larger debt. Rinse and repeat. Start with small life victories and gather momentum. Find a field that fits your personality, and implement the small steps, day by day to achieve that. Community college might be a logical place to start.
Three suggestions. 1. Stop drinking. If there's one universal truth, it's that drinking makes problems worse. 2. Stop kicking your ass about being too old to move ahead. Ridiculously untrue. I didn't visit SR and stop drinking till I was 38 years old, and that was 6 years ago. Plenty of other people address problems with alcohol at a much older age. Be thankful you recognize that alcohol is a problem at age 32. You've got a very full life ahead of you. 3. Be willing to accept your parents' help without this self-induced guilt trip while you launch your plan. Put your career plan together and share with them. Explain that being self-sufficient is important to you, and though you might need their assistance in the short term (and you thoroughly appreciate it), in 6, 12, or 18 months you fully intend to be on your own.
