Title says it all. I recently started this job (working from home of course) and things were fine. It was a somewhat seamless transition because I worked in a similar environment before. 

But now it’s starting to get a little stressful. I’m feeling myself have these subtle attitude fits when I’m assigned more work on the spot, specifically by my manager. I know that’s normal and a part of work—things come up and you have to adapt to the situation / reprioritize your work to do so. Constructive criticism is ok with me I don’t feel myself getting angry just mostly feelings of disappointment that I didn’t get it right the first time. But it’s these somewhat surprise assignments that are getting to me. It’s a salaried job and I usually work 9 hours a day or more but now I’m starting to feel overwhelmed. 

Does anyone have tips on how to calm down? Do you also experience this? How do I change my thinking around the situation? I never know if I’m irrational and being a big baby or if my feelings are even valid about the situation.
