Newly diagnosed, and feeling a bit lost

Hello community,

It's nice to meet you.

I received a diagnosis of autism yesterday. I'm 50, I'm in shock, and I also feel a bit like I'm falling into a deep hole of confusion. While I'm now glad to have a treatment framework to work within, I'm also feeling very sad that I didn't know about this until now, the latter of which seems to be a common theme I've read here.

Should I tell my extended family? Should I tell my workplace? Should I be open about it, or keep hiding my true self? I'm not sure what to do. I've been ashamed of being different my whole life, so it seems counter-intuitive for me to share this neuro-divergent diagnosis with neurotypical people. 

Thanks for reading
