New to fitness pal. Thyroid hell.

I'm Stephanie, I'm 31 years old. Married with 2 kids. I'm new to myfitness pal. My goal is 25lbs but 30lbs would be awesome. I have no thyroid due to thyroid cancer. Had to have it removed. Had oral radiation (rai131). I'm not fully in remission. But we are getting there! 🤞
So needless to say, my weight is a struggle. 😔 Just looking for encouragement. ❤️
