Hi Lori,
Keep the faith Lori, you should be ok. My wife just had a total thyroidectomy. We were expecting a partial / lobectomy but the surgeon saw more invasion of a larger than expected tumor and removed the whole thing.
Get second opinions and interview at least three surgeons who specialize in thyroidectomies. Interview several endocrinologists as well. You’ll learn more question to ask as you get more opinions. We did this and it really helped us prepare and feel much better about the surgeon and endo team that we put together.
Best.
