Hi HG, I hope that you are keeping a handle on those memories and niggling thoughts.
Believe me I know that is not easy; you'll have these thoughts despite not wanting to have them.
My P was in the same situation 2 days ago, company Xmas lunch during work hours. As he's working away I found it difficult to keep a handle on my feelings despite having confidence that he would cope. Know that my thoughts and hopes are with you now.
My P came through fine
he called me when he got back to work " Hi Darling, I'm back at work and I did great! love you"
