I am sad?

ok listen..
people dont answer questions like these because they are afraid to.
if someone tries to give you advice and it backfires somehow, well that would make them responsible in a way for the bad reaction.
so, that being said, you should consider seeing some kind of professional.
meanwhile, you need to know that you are not alone. and sadness isn't black and white. so in a way, everybody is really really sad all the time. its the human condition.
also, sadness is good in a way. it propels you toward happiness.
and a thing is what it is, but that doesn't matter. because a thing is what it is, it is only one way. but if a million different people saw the thing, they would each view it a slightly different way. a million points of view far outweigh the one way that the thing is, in reality. as such, things really are the way you look at them. if your cat dies, how long will it take for no one to care? in 100 years, no one will even know. its not really sad. all cats die. its only sad to you because its your cat. you dont get sad when a stranger's cat dies. why not? that cat is not in your universe.
this is infinity, and you must explore it. there is no time to be sad.
