Come undone

I am not so sure in myself anymore. I can clearly see, that I've become ignorant and stubborn. I can read it from my mind. I don't want to be like that.
Yet, everything is quite about perfect, so i have no idea why I am so depressed all the time. What more can I wish, if i have everything? I have the world, but that doesn't change anything.
The world inside me is still the same. It will corrupt me if i don't stand against it. I don't mean that it would make me "evil", just that it could hold me back. Could stop me from being free.
I feel that I've been imprisoned by myself.
I feel cut up inside.
