I've always been in love with this quote from the oft-forgotten Star Trek: Generations: "Normal is what everyone else is, and you are not."
I firmly believe that we, all of us, have some sort of deviation from the 'normal,' mentally. I went through a rough patch about a year ago after my Dad died (which, oddly enough, didn't kick in until about 9 months after he passed). For me, it was anxiety. I had panic attacks. Cold sweats, neck stiffness and pain, chest pain, dizziness, inability to breathe, spots in my eyes. Can't even recall all of it, now. I was able to work through it with some therapy and those happy pink pills, which I've now weened myself off of. I still struggle from time to time with flareups, but it's much better now.
Point is, no one should disparage anyone. You don't know how their mind works or what they've been through.
Oh, and that's Gillian Jacobs, Mr. Green (not to get too far off-topic).
