Just a small update: I got credit reports from all 3 major bureaus, and saw that 2 of them had some weird stuff that had crept up there that didn't belong there. I disputed all of the issued.
Just a few days ago, I was at the bank and they asked me if I wanted to apply for a CC. I said that I would like one, but that I doubted if I would be approved. She checked and told me that I had been pre-approved for $9,000. Let's hope that means my issues with credit are over.
