How do I deal with OCD over cleaning my house?

Im not obsessive over scrubbing everything with disinfectant...yet...but Im afraid it might come to that. I get major anxiety when things are out of place...It bothers me because I have 3 small children and when they bring toys out of their rooms to play I get very anxious and angry about the toys everywhere. I find myself standing over them and making sure they don't make a mess. They are kids and should be able to play with their toys without me getting mad over the mess of it. Im just afraid it will become worse. I litterally follow them around cleaning up after them, and watch over them while they eat with cloths and a broom to clean up after them. I HATE being like this. Its not fair to my kids!!! any ideas how to not be like this?
