I had a similar problem when I was younger. My parents gave me a credit card "for emergencies" when I was in my mid 20s and I maxed it out on stuff like subscriptions to online personals services. I did buy some stuff that I used for a while, but a lot of it was wasted. That was around 2000.
In 2007 I applied for credit cards because I wanted to start a business. I did spend about half of the total debt I accumulated on the business, which was ready just in time for the 2008 stock market collapse, and immediately failed. The other half, a lot of it was on junk food, I was pretty much living on burgers and fries and chocolate for a while and got very obese and sick. I also took a lot of day trips in my old Nissan. I ultimately declared bankruptcy in November 2009 with a total debt of maybe $40,000. My only income was an SSI check.
In 2016 my mom said I could have a credit card, and I was/am a lot more responsible, I didn't spend too much, and I've gotten my purchases down to a level where I can pay the whole bill with next month's SSI check, so I don't accrue an outstanding balance. I was addicted to junk food for years, and would blow through my check in two weeks due to poor eating. My check usually lasts me until the end of the month now.
My parents were always irresponsible with money, so I get it from them. They weren't to the extent of, say, Barbara Chandler, but my dad was always buying worthless junk.
