I remember being a child

[wildflowers1996]

and thinking adults knew everything. I trusted them. They understood how the world worked and had all the answers.
I'm 27 and still feel like a child looking for the adult to help me

I'm 36 and will never grow up

35 - I think the undiagnosed autism had a big role but for most people it's childhood trauma. You end up being fixed to that time point and don't "grow out" from it mentally.
So your example of having trust and it being broken (or outright lies) and rewired your brain to now see that for what it is.

To the masses grow up means - shut up, get a crappy job, be grateful you have a crappy job and slave away until it destroys your body. Same thing with the whole being "independent". If you are fucked from jobs, bills, debt, etc as long as you live on your own - you are an adult - congratulations- you beat the game of life - do
Not pass go. lol clown world.
