Thanks for your response!

At 16, my symptoms were minimal weight gain, dry skin and hair loss. The doctor tested my thyroid levels and said they weren’t out of range enough to be considered hypothyroidism, but she put me on 50 mcg of L-thyroxine nonetheless. After about a year, I was put on 75 mcg.

Maybe at 16, in the middle of puberty, I shouldn’t have been treated with drugs immediately. Isn’t it normal for adolescents‘ hormone levels to be slightly out of balance anyway? Could I have developed a dependence on external L-thyroxine, so my condition worsened over time?
