I think the hit and run incident will be looked at long and hard, unless you were a teen when it occurred. Why--because it is an example of when fear/panic/whatever overrode an instinct to show empathy and compassion. In most careers, it wouldn't be so weighted, but empathy and compassion are believed to be integral qualities for a therapist, and ones which many believe cannot be "learned" through training.

Excelling academically and being successful in the career are very different things. The former is a good basis for the latter, but it isn't an equivalency, in any career.

Why you stay with this T who appears to be incompetent, why you choose to be so enmeshed with her, why you seem to have an attraction to inflicting punishment and seeking revenge (based on your threads) rather than walking away from such conflict is a lot to figure out and change before you'd be able to treat others safely. It's not her decision to make and her comments are typically out of line, but it is a decision that bears serious consideration.
