I say hello to others and wish them well, it seems redundant, but on my downside somebody asked me, and talked to me, it made my life okay again. Try to get out more, even a negative douche, they still acknowledged you, and you must be different for that acknowledgment, imo that's good. They will probably go home and tailor themselves to be like you. I'm homeless right now but things couldn't be better after leaving my toxic parents. Cold but nothing like serenity.
