Scared........Biopsy.......Good New?????

Last week while at work the doctor I work with tried our new ultra sound machine on me. What she found were a few nodules on my thyroid and a enlarged lymph node in my neck. She told me it needed biopsied. So Friday I went to have the biopsy and the results were BENIGN!! Here is my problem, don't get me wrong benign is good, but what do I do next. Do I have surgery on my thyroid to make for certain it is benign all the way through or do I have surgery to take out half of my thyroid? If the surgery was done I would have to be on medication for the rest of my life, but I am sure I will be on some meds for the rest of my life with the problems I have now. So what do I do??????? I have no idea what to do. Yes I do pray!!!
