Dealing with Dissociation During Important Events

I try to tell someone about what it looks like when I'm having it happen and then usually they will try to get someone that can help me

I typically keep someone I know close to me, more often than not it's my partner. That way I can ask what's happening if I space out. For school I'd recommend having a friend help with note taking so if you miss something, you still have the notes. Or perhaps ask the teacher if they would be willing to share the PowerPoint or whatever they used in class
