In a most respectful and loving way I have to agree with your mother a bit. You do often complain and get very upset (pretty much devastated) over work issues that most professionals deal with every single day and it’s nothing really to write home about. There are no perfect work places out there. Your expectations of how work place should be are somewhat rigid and idealistic.

Saying that it’s maybe just how you are as a person. It’s just what it is. My husband tends to get flustered over same things at work that he knows are just how things are. My friend at work does it too.

Some anxiety or OCD issues might be playing a role here. Have you talked to your therapist about it?
