I suck at the emotions/expressing myself thing too... unless you piss me off! LOL then I go all New York. I love the little emoticons on here.. wish I could bring them with me to throw at T! They even come with definitions! Love it!
As much as I hate it journaling can sometimes help with that. A lot of times I also write a letter to my T between sessions. I have a week to keep revising it before the next session (when we meet weekly) and keep revising it over and over until it feels right.
