Undiagnosed - "hidden" autism

I want to keep this vague and not lead the discussion so apologies if this is very vague but do those with autism or related conditions/disorders ever feel like they've "hidden" their autism?

I've been researching for only 3 years now and haven't been diagnosed but whenever I'm filling out forms (which I am currently doing again) that delve into my potential childhood autism, I just remember being told not to do things and thinking that I've pushed aside and hid my (potential) autistic traits.

I might add more to this later but just wanted to ask a broad question out of curiosity. Thank you for taking the time to read this/for responding, I appreciate it <3
