It depends on what you mean by "special". Based on the fact the character can take care of themselves, I wouldn't say their mental disability is overly-crippling, and I honestly do not mind people roleplaying these types of characters as long as they are realistic about it. However, you must know that you might step on some toes. The RP community is the tumblr of story-telling and videogames. If people can get offended about it, they probably will. That said, as long as this "disability" isn't all there is to your character, you should be fine. Make sure to give them a personality and depth.
