Why I can’t be happy?

I have everything I need and I’m still not happy with what I have, I don’t even know what I need anymore, I got a house, a car, some money, two parents who believe in me, a little brother that hates me and what is left?
I feel like it’s something missing I still feel it deep down inside to my core self.
I still think that something is missing from me but I don’t know what, like it has been stolen or something like that.
I need more, I need more truth, more love, and affection, and pleasure, I need more life, I need myself now more than ever.
I need to know the truth of things that have been yet happened.
I need to know it all.
I need to know how things work these days, I need to wake up, I need an awakening to happen, I need you guys as much as I need myself.
But what is missing deep down into my core system?
It’s like you’re never there for me when I need it the most.
It’s like you left me for granted.
It’s like being abandoned by someone.
It’s like loneliness when you are surrounded by people.
It’s just like depression.
