Obsessive thoughts and anxiety?

Alright, so, recently I have become an overly paranoid obsessive thinker all the time. I always think that there is something that I am not remembering and that I am missing vital details of something or something terrible had occurred that my mind just isn't grasping for some reason. For instance, I will go out for the day and run a bunch of different errands and then I will come home and think to myself "did something terribly wrong happen that I can't remember"? Its usually harm that I worry about like "did I harm someone while I was out but can't remember it now?" or "did I get my azz kicked but can't remember?". Is this at all normal and are there solutions?
