Late diagnosis adults with Autism

I'm 33 and going through the Diagnosis process currently. It's very hard going. Going through every inch of my personality and life. I'm struggling with trying to separate what is me and what is autism. Some things I do, like or find uncomfortable will just be my personality everyone is different. Which bits are and are not  Autism. My family and friends argue with me on certain points that everyone does a little of everything.  I work with Autistic children so I'm fully aware of what Autism looks like as a spectrum. However i feel adults are a different thing all together. Ive had my whole life to learn. hide and adapt to the world around me. I'm now set in my ways and routines and have found safe ways of doing things for myself. I don't know what I'm hiding or masking anymore. To conclude who I am? 

Help ? I don't know any adults with autism to reach out to
