PrisonDude,
It's just hard not to comment on this one. Skip what I'm saying if you don't want to hear what I think, because I'm going to honest about what I think.
You say you have bad credit, which translates into having borrowed money and not repaid it. That means, when you have unfulfilled promises to repay money you owe, you feel that strangers should pay for an expensive, luxury item that you want simply because you want it.
I hate to break this you, but you aren't the victim here. There are a multitude of choices you have made in the past that have put you where you are today. Those choices would have been essentially the same had X, Y and Z not happened to you.
I don't think it's ever too late for change, but that begins by taking responsibility for your decisions and making choices to be responsible for yourself, and to keep your word to the best of your ability (including past promises). We can all grow, and I've found that in my attempts to become a better person I become more, rather than less, successful. Sometimes that costs me money in the short term, or doesn't seem to have any identifiable return benefit to me, but in the end it absolutely pays off.
Honestly, I wish you the best in the future, and hope you are willing to create that for yourself, because it isn't anything that others can give you in a meaningful way.
