I'm not sure if I have SPD, but something schizoid like has definitely been going on with me for a very long time.

I never had a problem with my weight, my strength or athleticism though, I always considered myself at least average in these areas, though in some aspects I go beyond average, as I do lean towards being explicitly sporty, I actually seem to have talent in some sports, and I like to put my strength into things.

Again, I'm not sure if I have SPD or the symptoms are the result of something else instead, overall I'm not at all like the stereotypical schizoid if you look at me.
