So sorry for your loss of your dear mum. Witness funerals are no comfort, I know from experience. My mother died 2 years ago and she was an inactive witness, nobody showed up for her funeral. On a positive note the whole biker club my brother is a member of came. They were all in their leather jackets and came with lovely flowers. The priest we had arranged to give the ceremony did not blink an eyelid, took it all in his stride. I would have loved to have seen the faces of the witnesses if it had been in a kingdom hall.
You are now free to live your life exactly as YOU feel fit. Go for it!
All the best wishes
