I am 21 years old, I grew up in foster homes and group homes and when I was 17 I was at an airport quickly running to port, and someone stopped me and asked me a bunch of quick questions and I remember them asking me about my income, and I got insecure and lied about how much I make. Later on when I was 19 I applied for a credit card while I was on welfare and disability (psychological disorders), and they approved of a $500 limit (I get $900 a month). And then I get another card a few weeks later in the mail with a $2500 limit. I grew weak and gave into the craving and spent all of it like a fool. I am now 21 and I stopped paying it because I simply cannot afford it. My caretaker then told me that they did not perform there fiduciary duties because I do not qualify for $2500 credit card (I only get $900 a month). I just don't know what to do, im scared and every time they call me I don't now what to do, so I ignore there calls, but it makes me afraid every time they call, what can I do to end this?
