I don't know how conversion would help you if you are only paying for secured debt. Are you saying you want to give those things up?
I remember you posting about wanting a secured Discover a few days ago. If you don't have enough money each month, how were you going to fund that? Also, I remember you getting credit from Penfed a couple of days ago. Why are you getting credit if you are in the negative. It sounds like you just want out of the 13.
Actually you posted a screenshot about Discover secured while in a Chapter 13. I responded to it. All I know is what you post. Best of luck to you with whatever you do.
