Just got fired from my first call center job.

And it was the best job I’ve ever had, I know a lot of people hate call centers but I would just book appointments with patients and I’ve never had a rude one before. I feel like shit, I did a mistake and I got canned. My contractor told me they would help me find another job. Do you guys think its true?? I feel like absolute shit, especially with my mom. I feel like a failure.
