As a doctor, you hadn't stunted your growth. Hypothyroidism doesnt go away on its own. Low T actually should have made you become taller as sex hormones cause the fusion of the growth plates. You are simply a late bloomer (and it is obvious from your photos as you still look like a teen). Take the T prescribed to you and hit the gym. Low T is linked to depression and low self esteem in men so taking it will also alleviate your low mood
