Welcome to the club.
(((((((((((Ipse_Dixit))))))))))))))
My (former) T always was telling me to "stay with my feelings" and that I was allowed to feel them and express them and I knew I was a tad emotionally bottled... but his homework for me to do that every single therapy session was REALLY hard work.
I think there's a difference between knowing an emotion is there, between feeling the emotion, and then letting yourself outwardly express it.
I for one cannot seem to get angry. I can feel angry, but instead of directing it at people, I direct it at myself. I don't want to let myself feel angry because then I feel out of control. If I'm not in control, I can't deal with the situation. So my task is to try and allow myself to be visibly angry at people who (righteously) deserve it. Still not working well, people think I'm joking.
I guess I don't make much sense, I'm sorry.
Hope you find an answer to your question.
