A little information about me before I start rambling.
I'm married happily married, I have a toddler the age of 18months and I'm currently not working, I think I might have some severe insomnia every night I never sleep I always overthinkink about life and it's pointlessness sometimes like today I questioned my existence in this vast expanding universe and how little or pointlessness of human existence is like we are just some being living in some floating space rock that contains life ? And we create all this problems on ourselves? Why must existence be so damn confusing ? What the heck is existence in this vast expanding universe? Why am I here because of sheer luck that I was creating out my dad's seed? What is this what is the meaning of all this. I know it's pointless thought but makes you think how puny human life is and how insignificant we are I don't know why I have the urge to have these thoughts at 2 in the morning as I am typing this. See these are the thoughts I go through at night when I'm trying to sleep hence why I take forever to comprehend it and makes me stay up all night just thinking about it. I love my family my wife and son but sometimes I just find myself in this situation of what's the point in this ? Why must human existence be so complex yet so meaningless? 
I've had these thoughts every night when I go to bed and kept it hidden from my wife because of don't wanna sound depressed but I wanna just want these these thoughts gone so I can find a meaning to existence as a human being for my son's sake and wife.
