FEMA CORE question. Accept or Decline?

I have a start date of March 10th for FEMA as a CORE employee. This will be my first government job after applying for 8 months. However I am so nervous with everything that’s going on. I was let go from a job in April 2024. I wasn’t able to find work again until November. So I have a job but I really want this FEMA job because my goal was to get a government job and I’d be getting a bigger salary. I really don’t know what to do. Like I don’t want to start another job just to lose it.
