Eeek! Eeek! LOL
I have the same issue at times, feeling as if I did something wrong or as if I failed, when the reality may be quite different.
When my T and I had a major rupture not too long ago, he told me to stop emailing him.
After we worked towards resolving our break of contact, the boundary changed, somewhat, to where I can email him - but if I am unhappy with him in any way, I need to address it face to face and not in email.
Of course, I felt as though I did something really, really wrong to have him set this new rule put upon me. But in reality, it was not serving me to have an email exchange with him when I'm upset or angry with him. So, I know it was for my own benefit.
I'm glad you're more calm today. I'm sending you Mighty Mouse vibes....
