A lot of my anxiety revolves around the workplace, feeling concerned about making a mistake, missing something, offending someone and overall perfectionism. I check dates and my schedule multiple times. In addition to GAD, I also have OCD that revolves around checking things.

Even when I know I’m doing a good job I still get these feelings.   
I’ve worked at my current job (teaching) for 4 years and still feel insecure about it. 

If I make a mistake, my anxiety spikes and I ruminate on it for a long time.  
I'm very concerned about how I appear to other people - do I look irresponsible? incompetent? 

I see a CBT therapist who is wonderful, but I can identify these issues as core fears that I think I'll be working on for a long time.   
For me, a lot of it is due to the fact that my parents were in an unhappy marriage and were very critical of themselves and us. My dad had a temper too. My siblings and I were given a lot of responsibilities at a young age.  
Wondering if anyone else is dealing with similar feelings and how they cope.
