I can very much relate. I am usually like this for much of the day after my session. Especially recently. I go for lunch in the cafe in my T's village after my session. I'm a total regular there now which brings with it it's own problems as quite a few people in the village know me and want to chat.
Even though I pick my kids up from school three hours after my session I'm still not really ready for the trials of parenthood. Or to hear about H's day at work. Therapy days are hard.
