alone in my thoughts

I was feeling sad, and I never elaborated, but rather changed my mind and affirmed that I'm happy because I have a family that makes me feel like life has meaning.
Silly how the sadness lingers though I am grateful for all that I have. I can't say I have any regrets in my life for I have all the important things as a result of series of events that were not all pleasant. Well, a few of them were very pleasant, but navigating there took a few detours from whatever it was that I thought I wanted.
Anyways, I think my sadness is rooted in my sort of perspective being absent in the things I encounter or that I lack the logical leap ability to understand quite a few trending memes or such. I have friends, but find myself wondering how I can be friends with them when they believe things that totally conflict with my perspective. Almost feel like I'm an alien or the like where my up is their down.
