Giving away my session time to someone else makes me feel like i was kicked in the stomach.

I told you that treatment was only temporary and there was no other time i could do it. Why didnt you bother to ask me? Ive always been flexible with the schedule when you needed me to be.

Feeling really hurt. Why would you do that to someone? Or am i just being overreactive and dramatic again? Im confused why i shouldnt be upset. Its really confusing
