I mean you have two options here. Stay at home and worry your head off. Go see the doctor have tests done and worry your head off. Both ways you will still end up worrying your head off. You may as well find out what is going on and if the lumps are anything. I would rather worry over something than worry over nothing. If the tests are all good you can simply put your mind at ease. Until you find out you will worry your head off. Best to go along and get it over and done with. You are thinking the worst. It may be nothing at all. Let us hope so. Then you might learn that you can worry your head off all you want over nothing. In other words best to try and not worry until we know something for certain. You are ten steps ahead of yourself right now. Try and remain in the moment. Let the hours pass. Find something to do.
