because no one cares for your sob story. no one wants to hear your negativity and no one has the time for that.
they want to suck the happiness and success out of you, like a vampire. and if you have none left, society sweeps these empty bodies... mentally abolish these people so even if youre sad, lonely, dont show it. dont let people know... just pretend to be happy shiny and glowing with positivity even if you have to fake it.
