High masking self v Authentic autistic self

Does anyone else who's high masking feel like there's such a massive gap between the external presentation of self to others and the internal self. Even with those closest to me. 

It feels like the bigger that gap has been, the harder the crash during burnout. It feels like there's further to go for me to get my true authentic autistic self. 

I was self diagnosed for 9 months before got official diagnosis. I went for this mainly because I was so good at masking (which I'd just found out about) that I didn't think anyone would believe me that I'm autistic!

I suppose I'm now in the period of shortening that gap!
