As with most holidays it can be a struggle for some to celebrate and even be triggering for some. I still have my mom and I'm very thankful for that, though I know I need to be more involved with her before it's too late. Actually she my only reason for going on. Maybe that's why I in a way fear being around her , that she will leave and I will go with her.
But if you have a reason to celebrate with your mom please do.
