I'm on vacation in another country and got burned out with socializing after finding myself in spot dominated by potheads. I then moved on but went seven days without having a single conversation with another person. I still had some human interaction as I had to ask hotel staff for a room and how much, and order food, etc, but other than that I didn't really speak to anyone. I realize this is not normal, but I also don't feel like it bothered me at all. I honestly didn't even think about it until today when some Polish girl started talking to me.
Should I be worried? Does this sort of thing point to any sort of mental illness?
