To me, seeing happiness or positivity (fake or real) online is really startling-- even more startling when directed towards me. Seems that in the end, regardless of whether everyone wants to or not, everyone is some degree of starfish, me notwithstanding. So that, in combination with a naturally cynical mindset I have, clashes with experiences of seeing or experiencing positivity. Even a simple "<3" or "hiya", when sincere, just takes me off guard for this very reason.
