Definitely keep busy and when you mind goes to the "what ifs" try to just limit the time you think about it . . . like maybe 2 minutes (or less) then switch to something completely different. Stress itself can affect your health, so it's important to try and get a grip on it. Waiting and worrying about something can really be a crazy-maker. So think about the positives like the maxillofacial surgeon saying it looked non-suspicious. Once you find out for sure what it is (and it may be nothing serious) you will feel a lot better and can start doing something about whatever it is. For now, do something fun with your son, exercise, deep breathing and getting together with friends helps. Hang in there and keep in touch with us here.
