Yep. I've been there, many times. Just when I think that I am going to be able to have a conversation without crying, and actually go a couple of appointments that way, lo and behold, the tears show up again.

I notice that the tears are more plentiful when I'm talking about hard stuff that I've been avoiding. The few appointments after the hard ones are where I seem to be able to talk without tears.

It will get better! Don't worry, I'm sure your T is used to it!
