How did you choose your goal weight?

I'm trying to decide a goal weight.

I'm 12 stone now (after 6 months, 24lb down, on 1.0), and in my younger years my body naturally settled (between diets) at 11 stone 6lb. At that time I would have been a size 14/16. I'm currently a size 18 with more fat around my tummy as I'm not able to exercise (I'm now a very fatigued wheelchair user). My healthy BMI is 10 stone 10lb.

I want to give myself the best chance to maintain over time, and probably don't want to have to continue paying for wegovy for life.

Does anyone want to share how they decided their goal weight, to try to help me?
