TW: Grief/ Death

My grandmother passed away last night. I'm ADHD and possibly autistic in a family that has no idea about what that means. We found out she was ill recently and I haven't heard from either parent for support. I'm devastated and coping today.

Now comes the next part, the funeral. The masking is going to be insane. I'm going to want to make connections with people but I have to constantly be on edge so I don't say something stupid.

Anyone have any tips for dealing with the grief and funeral?
