Just because somebody says they are happy does not mean they are. Maybe they are even more desperate than those of us who admit it. Maybe they fear loneliness so they rather suround themselves with shallow people they may not even like than to be with themselves... who knows. It does not matter in the end.

I believe happiness comes in short doses... nobody is happy-happy-happy all the time. And the pursuit of such constant happiness can hold us back... because we become disillusioned when it does not work.

I do believe depression and other woes are existential to a great degree... so yes, we are predisposed to them by being humans, having intellect and knowing our time here is limited and that in the end, we are very powerless in this world.

Take your time to mourn your loss... and don't blame yourself it takes time... it is normal to feel that way. It can take quite long and it will always be there... but you would not want to be so shallow to forget and go on happily without any sorrow, would you?
