I'm not sure i understand being upset about hurting your T. Her JOB is to deal with your emotions.
If a horse kicks me and injured me, I don't expect the horses owner to feel bad about it. My job involves putting myself in the firing line of unhappy horses. A T's job involves putting themselves in the firing line of unhappy people.

If you were abusive, threw/broke things, threatened her etc I guess i would understand. But your T needs to be a big girl and take care of her own feelings, not make you responsible for them
