I'm 95% sure I have autism, but was never formaly diagnosed, nor tested for it. My parents never bothered taking me to a therapist, hell, I don't think they even know what autism is really. My life would have been much easier, had I known from an early age on what was wrong with me. Since I had no refernce point to assume otherwise, I would instead gaslight myself into thinking that I was normal and blame my (conscious) self for not trying hard enough, which would lead to a sprial of anxiety and self-loathing. Even now that I'm writing this, I feel like a faker for claiming to have autism without an official diagnosis, but many of my symptoms are so obvious that I just can't live in denial any longer.
Not a single person in my life knows about this. I'm a shell of a person. -- Never nask, kids.
