Diagnosed with Hyperthyroidism and Hypothyroidism: Anyone Else?

Hello, has anyone else experienced getting diagnosed with hyper/hypothyroid and then later getting diagnosed with the opposite? In 2019 I was diagnosed with hyperthyroidism. I have consistently had a thyroid nodule. I started seeing an endocrinologist that year and started doing bloodwork and getting ultrasounds on my thyroid done every couple of months. I was on Methimazole for about 2 years. My bloodwork started improving and so the doctor took me off the medication. The next time I went for bloodwork they told me my numbers has done a complete 180 and that now I had hypothyroidism. My body has been through a lot, I lost lots of weight and then I have gained it all back and more and I'm struggling with it.
