I feel better this morning! I read about CBT yesterday evening. It made me think about that, I have been shy since I was a little child. I was also and still am (to some degree) very kind. I think it was that part of me that became hurt Sunday. So it is more some kind of self-love and acceptance that was needed in that situation, to comfort the little child within and accept that I am who I am and that is OK.
The weather is not the best, so I will use this day, first of all, for physical exercises at home, then for cleaning.
Best wishes to all!
