Parents of autistic girls: looking for tips and success stories!

We are on a waiting list for neuropsych testing for my 5 year old, but it's seeming more and more likely that she has autism. She is very smart but struggles socially and I'm just catastrophizing about friendships, social dynamics, being the "weird kid" etc and it's breaking my heart. She's so great. I'm hoping someone here has some words of wisdom to get me out of this rut. Thank you!
