Getting diagnosed (input wanted!)

Hello friends

I have just recently acquired health insurance and I’ve been considering going and getting professionally tested/diagnosed

I’ve done my research on my connection with ASD and I personally want to go get professionally diagnosed, but I’m worried it won’t go well since I’m going to get diagnosed as an adult

Would it be weird if I brought my own research and notes on why I believe I have ASD I genuinely want to bring in a binder full of notes and research and my own personal experiences as to why I believe I do

(Also: I want to get diagnosed for my own personal reason, not for others. I just feel like my whole life I’ve been wondering why I feel a certain way and I feel like an official diagnosis would give me “closure”)

Pls feel free to give your input thanks all
