Is it possible for your mind to be dissociated from itself and blocking large parts without other personalities?

Im not running on all cylinders...

I feel stuck in time with separation from life experience and memories and memory processing?

But im so used to it because i have alwsys been like this.

That i forget...

Does anyone know why a mind would collapse like that?
Or how to make it better... or learn to live?

I need to get myself together because i want to move out soon..
