Crystal prision

Sometimes I just need to be here all alone and isolated. Think about nothing and everything at the same time. Slowly watch my mind blow a thousand times in a minute.
I know what to do, how to solve all the storm of problems around me, but something is not right because I'm never able to fix the problems, and they keep increasing as long as I do not solve them. Maybe they  are not really increasing, it's just my mind blowing once again. How long have I lost in these thoughts that hold me into a kind of crystal prision, where I can see outside and interact to other people, but I'm still a prisioner of my own mind.
I would like to know how long will this duel between me and myself last. I can just wait for the end.
