my T has told me time and again that emotions are like waves, they come and they go. Because like you, exotic, when I started to feel I couldn't handle the intensity of the feeling. And I still get caught up in my thoughts about what I'm feeling, especially if it's a difficult emotion I tend to think "omg, I'm going to feel like this FOREVER, it's not going to stop!" whereas when I'm happy I think "oh, this is nice, but it's not gonna last"
Anyway, my T has really stressed with me the importance of remembering that emotions don't last, even the really really big ones, they don't stick around forever. Even the flashbacks and the terror, it comes and it goes, and not only that, but it goes away sooner if I just LET IT COME.
That was, IS, so hard for me. I want to tense up and brace myself for the onslaught of emotion and clench my teeth and my fists and resist it, but if I can relax and open my hands and let it wash over me, it's not so bad. But wow, that's hard to do. My poor T has to tell me time and time and time again. Sigh. Someday it'll sink in. Maybe?
