Hypo is 'safer', and if you have a really good thyroid doctor, who is open-minded about prescribing the proper dose and type of thyroid hormone, hypo might be the better of the two evils. The problem is that there are so few of that type of MD in the world. They so often want to keep us undermedicated.
Your main problem now, as I see it, is that growth in your neck. When a hypo person's thyroid expands, the right dose of hormone can sometimes keep it from getting larger, or may even shrink it. Obviously, you can't take any extra hormone. I'm not sure that leaves you many options.
How is your hyperT being controlled now? Are you on anti-thyroid meds? If so, are you sure the dose isn't too high, causing your gland to swell in an attempt to provide more hormone to make up for the possible overmedication?
I'm not personally familiar with hyperT, nodules, or goiter, so I don't know how to advise you from here. I can tell you that there have been several members here over the past few years who've had total thyroidectomies and done very well afterward, due to the excellent MDs they had replacing their missing hormones.
I wish you the best in making your decision.
