No doubt. I have several friends who have. I have thus far been spared. I would wish that on no one. Those people in particular have had to make a choice to heal and to be happy, and no one has worked harder. One started a charity, to teach young people to avoid the sort of accidents that took their children. One started an event to raise funds for a charity to deal with the disease that took their son. There's always the hole. They have chosen to use the hole.
I have not been so lucky. It is, in fact, a life changing moment that never leaves you. Make no mistake, your imagination will not cover it. When you lose both mom and child,...it will spike you hard,... forever. You will look at life, death and time much differently. Negative people are a vexation you can't push away fast enough nor hard enough, however ridiculous. No one needs a cherry on the top. Surround yourself with decent humans with positive attitude, people who have empathy, because ya probably can't take anymore negative in any form. So when I get nasty, and I will, it's because someone brought negative to my dinner table. Life is too short to settle for one minute of nonsense. OTOH, it would be very hard for anyone to top what you've already been through, no matter how crafty they think they are on getting to you. When they think they have, they actually haven't even moved the needle.
Advice: don't make them relive it by asking what happened.
