Hello,
Someone please tell me IABU to be thinking like this. Yesterday I found a mouth ulcer on my top gum it's tiny- only a few mm across but because it doesn't hurt and it seems a tiny bit sunken into the gum I have convinced myself it is cancer. I do this everytime I find something abnormal and it ruins my life. Instead of enjoying my toddler today I am rubbing iglu into my gum while staring at the mirror every 5 seconds to see if it has gone yet.
