Welcome!

You are in a very knowledgeable, supportive place to start to make sense of it all. It is not uncommon for more than one family member to be affected, which is the case in my family, it is scary to see the effects in so many family members.
What is nice about this site is there are many resources. if you want to learn more about diagnosis, treatment, tools to support, ect. A good place to start is with the post pinned at the top of this page. Some of those tools have the potential to help stabilize things, not make them worse and maybe even improve!.
If you want to talk to people you can post here and read other parents experience, nice to not feel alone.
Can you tell us anything more you are comfortable sharing about your kids and you? Like how old they are? Do they live with you? Is anyone diagnosed, ect
So glad you are here
