Obsessive compulsive disorder is what you describe. Of course the disclaimer no one can diagnose you online. And no, it is not normal. In some cases people live with a slight and stable disorder which is not too alarming, but if you are fairly young and the behaviors are increasing in number, getting targeted therapy is a really good idea, because OCD can feed into itself and soon got you pretty trapped. It's much better to start while the behaviors are not overwhelming.
