We already withdrew earlier this year and it was a huge sense of relief to finally walk away from incredibly unhealthy but it was hard as well. I think the sadness is grieving the loss of how you imagined parenting/childhood would be for your child. Every parent has dreams for his or her child. I can't imagine anyone's dreams look like the realities of EG/PG/2e, etc. There is a sadness in losing the dream of how this would look and feel and a reality of how hard it is and that there may never be a "good fit" with no trade-offs. It's the sad reality of living in the tails and being so far from the "normal experiences" of childhood.
