In most cases others dont have intention in making you miserable. They are just being themselves and say things that may seem directly aimed at you. The universe, however rich in informations may seem, is packed into few basic nodes, and we also pack things into our own little explanations.

Of course there is always that annoying or triggering bastard you can come across and that really wants to make you miserable. And sometimes you can even learn something from that misery they cause you. But in the end, ignoring them is the best option.
