I need to vent

I’m so upset and just want to vent and get some advice. I had a really terrible day at work. I’ve been struggling with my mental health when it comes to my job. We are extremely short staffed and I’ve been working so much over time. And I’m so exhausted.

Today, a customer was extremely rude to me. And I tried to help her. She left and called into the office a couple hours later and complained about me. She called 4 different offices and talked to those managers to complain about me. I was so embarrassed. I’m not in trouble because my managers believe me. But I’m so upset that this lady tried so hard to get me in trouble when I did nothing wrong.

I’m so burnout. I try to find another job.
