To remove or monitor, thyroid surgery?

I am 42, female and I didn’t go in thinking that I had any sort of cancer,  just lower thyroid hormones and all the symptoms of that, BUT they found 5mm thy3a nodule: so instead of any solutions for the symptoms I have this new heavy question: remove or monitor? Please, please,  anyone that has hade a thyroid lobectomy please share post-op experience, did you have to take Levothyroxine? How has that gone? Did anything get better upon removal or is it just the relief of knowing that you don’t have that ? Anymore.
