Anxiety allover the place

It is nice to be prepared for the the worse, in case something happens.. but I hate how I always assume something bad is going to happen, something will go wrong, with and without a reason. I am not sure why I am always so pessimistic.. thinking, it is not possible that everything will go well .. I literally look for what is going to go wrong, and if I cannot find something, I make up something...

This is LITERALLY my brain, me; what could possibly go wrong, just casually wondering.. my brain: Excellent question!
