Paid off a bill I thought I would never clear - any advice?

My first paycheck after 8 weeks arrived today. Any experience at all would help. It is a small amount, but it feels huge. Hoping it is the start of a better run.

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

Keep everything in writing and save the confirmation numbers. It saved me later.
