How does not going to your next appointment, or going and not talking punish your t? Seems like that would make things more stressful for you. If you can't talk about what's eating at you, your feelings are just going to continue stronger. Do what's going to be best for you. If you see no point in continuing with her, maybe it's time to cut your losses and quit. Maybe you can find someone else who better matches your needs and can be of better help to you.
