How do you talk with your child about getting them assessed?

I was recently diagnosed with autism, and it was not something I suspected until I broke, last year, physically and mentally and my therapist clocked out and had me assessed. Being a woman in my 30s, it's created a big mind-f* of unpacking my entire life and seeing so many things that should have been obvious to everyone around me.

Now I'm looking at my 11 year old daughter and recognizing her struggles as being so similar to what I experienced.

So we are having her assessed. She shouldn't have to go through life the way I did, thinking she was just weird and wrong and then have to unpack it all as an adult with a broken down body and mind from 35 years of masking.

How do you talk to your tween about this? She's so sensitive to changes (go figure) and meltdown over medical environments, appointments, etc.

Any advice is welcome.
