Am i the only one who suffers from existentialism depression?

Looking back in history, it gives me shivers to think if I had been borne in most societies of those times, with their constrictive mindsets. The same is true for many societies today, including right-wing America. By choice I have sent the last 40 years, my entire adult life, in a distant culture very different from the one I was brought up in, enabling me to see "my own culture" clearly for what it is. The memes of all societies need to be seen and examined, few are worth keeping as is, but just the first step - seeing them clearly - is too hard for most. Consider yourself lucky that you smell something funny. There are a lot of us who made it out and now enjoy every moment of life.
