Wilma,
Most of us here are very familiar with those same feelings. Since my cancer, I have gotten myself into a near panic on several occasions. Anxiety, lack of sleep, loss of appetite, etc. Things that appeared to be serious (to me), turned out to be nothing at all to worry about. Not to minimize your condition, by ANY means, but there are numerous possibilities other than cancer. Hang in there and I hope the results are favorable!!! My thoughts and prayers are with you!!!
