I have the same exact thoughts sometimes! Despite my pain-staking measures to try and bury my symptoms six feet under and pretend I'm fine, I constantly question if I'm actually "unwell" or not. What if the past seven or so years was just the result of out-of-whack puberty hormones? What if it's all a desperate and elaborate ploy by my inner subconscious to try and be "special" and get attention? What if I'm just a wimpy faker? And then inevitably I end up doing something stupid and then coming out of it and thinking "Oh...yeah. That wasn't my proudest moment. I think something might be wrong with me, maybe."

You're not alone.
