I've asked before for the trolling to stop, I won't ask again. There is no need for anyone to follow any member of this forum around and people should remember that this is a unique forum dealing with all types of different personalities and disorders. Be decent and respectful toward one another, if you have nothing to contribute then don't, it is that simple.
As for the original question here, yes you seem to be overthinking it which you are not alone in that, there are many people here who have the same problem, reading too much and over thinking everything. Like others I've gotten that "you look like so and so" when I couldn't see any resemblance. People tend to pick up on the slightest thing that reminds them of someone, it could be the smallest of details like a persons eyes or nose or the way they smile. It doesn't always have to do with being identical to another person, which is annoying when you do have a twin running around and get mistaken by strangers for them.
