Growly,
I hear that you yearn for someone (Kashi) to care deeply for you. I hope you are able to tell Kashi that you feel this way. You didn't do anything to the person who s.h's, that person's reason for doing it is still valid. And it is valid that you want the same deep care that your T showed to the other person. I hope you are able to be kind and compassionate with yourself, as you so deserve.
