It's the perspective of your rational mind that is creating it. The mind finds it easier to be the victim, so it says that everything else is causing sadness. People are cold, they don't understand, I'm this or that and have been dealt bad cards etc. Settling into the mind-frame where one is the victim feels safe, and believe it or not, we find comfort in that state of mind because of its familiarity. The sadness is a familiar state that we can fall back into. I went through all of this. Transformation will happen when, for whatever reason, you simply realize that life is beautiful and great
It can't ever be articulated so that one day you just get it. You just keep working with the catalyst until that transcendent moment of realization is experienced. A lot of it has to do with the pull from the societal mind..what society values and why it is supposed to make us happy..the "meaning" of life.
I really suggest spending time in the sun and nature. Sun helps heal depression, and nature will uplift and nurture you.
