From google. 

I have been giving way to anxiety. I have allowed my mind to dwell on difficulty.
I let my mind got lost in negative thoughts, in all possible ways of difficulty.

I let myself got exhausted
I let anxiety took over

I do realize though, that this has to stop
Because all of those things are not real
They are just playing around in my head

Stop.
