Interviewing for my dream job. Im on the background check part. Pretty sure my dates of employment were off by one month for two jobs. 

Additionally, HR is asking me to get a letter of employment from my old employer as verification. Old employer is dragging ass, as they are government based.

I have my records of employment, but they want the letter. Im freaking out. Everyday is me checking emails and feeing constant adrenaline.

I need help. I want this job so damn badly.
