AITA for constantly using my family's credit card ?

So I don't have a lot of money since I don't work and I recieve very little pay from my monetization on one of my youtube channels for a specific niche of mine. This channel is only raking in about at max about $100 every two months or so. Because of that, I have resulted in using my family's credit cards to buy things for myself. The card is sitting in quite a bit of debt. I recently had placed an order to get a custom made traditional chinese dress made so that I can use it for one of my upcoming films. The tailor ditched me after I paid her and she is not picking up the phone. I drove all the way to the city where the tailor is at, a freaking 4 hour drive to see if I could come in contact with the lady. Her shop was closed and the lights were turned off, even the coffee shop that is in the front that she owns was closed. A lot of people online who have been messing with me has claimed responsibility for this by claiming redirecting packages or talking to the tailor which is bull. I don't even believe one bit that these folks had anything to do with it as stealing packages is a federal felony. I don't think any postal worker would risk losing their job and getting federal prison time over a $200 package. I stopped by another place to try to get one and they had none in my size, the biggest size they had was XL. I now am having to look into getting one made from a service on Ebay or Etsy now as I am crape out of luck now as I need a freaking dress for this role and for my drag performances. The ones that I have are made of velvet and is too hot for this summer weather in my area. After begging my family for hours, they finally agreed for me to look into one service on Etsy to try to get one made for me. It's literally the only option that's left and its going to cost more than what the tailor charged me for but I have no choice. My friends say that I'm an asshole for continuing to swipe the credit cards. Am I the asshole for doing that ??
