I wouldn't automatically assume disability has something to do with it. They came up to you to begin with, right? I would bet most of them just feel like they owe you something now, or you are going to ask for something in return at some point.
Don't let it bother you. People are strange, but at least now the people you've met aren't strangers.
I don't think you need to be told this - keep being you, there's no one else that wants the job.
