Echos Myron... I agree that you are incredibly brave for managing to ask your T for a hug! I can't even imagine! Please, please do not lose the *awesomeness* that you were able to ask for what you wanted!
And... I hope you can go back and talk about it. Hopefully he can explain in a clear, non-awful way *why* he didn't want to give you the hug.
(((hugs)))
