Bot flies...? Unng.. nevermind.
Don't want to know But no really, I don't think people think it's silly, I just heard it was sort of almost a "trendy" phobia. That people wanted to feel like special snowflakes because they were slightly grossed out by something.
But no, That's the problem! There's people out there with a legitimate psychological reactions to these things like you and it ain't right to just assume they are overreacting!
But it doesn't mean you should hide, really. You can get help.
