The thing about changing an email based on someone else's advice: The email may or may not be appropriate in social situations - and I'm not critiquing this email in particular, this is a general statement, but it's eliminating a potentially valuable source of "therapy fodder". Like, what are the projections embedded in the email, what are the feelings, etc. Writing on the assumption that the therapist needs building up or is prone to judge or get hurt by criticism, whether fair or unfair, is putting someone else's therapy fodder in the email. Not useful to the OP's therapy.

It's like... about 10 years ago when I was a volunteer English tutor an ESL learner improved so much between the initial in-class evaluation and the first home assignment that I took the samples to her professor and asked how this could be and did she still need me? He glanced at the second sample and said she had help doing it. Great for her initiative but I needed to know what help she needed.

Seemed kind of similar to this.
