Oh I can SO relate to this. I feel GREAT when I have all this energy, I accomplish so much and just feel peppy... but when I look back on my actions a few days later (what I can remember of them anyway) I am so embarrassed of how much I talked, how I am unable to express my ideas and thoughts and just stutter and repeat myself, how I do silly goofy crazy things... I bounce off the walls and it's fun while it's happening but it's embarrassing when I think about it later.
I don't have a way to contact my T outside of session but if I could I would do the same as you, call her and apologize for not being able to focus and for being crazy, haha.
