Struggling with Hypothyroidism and Fatigue: Any Advice?

Hi, I'm new here and was diagnosed with hypothyroidism in March 2022. I have been on levothyroxine since then, but I am still experiencing very severe fatigue. I also have been trying to lose weight and have tried changing diets, etc, but nothing seems to work. This is causing me to be very low in mood, and I may also be experiencing early onset menopause, which won't help. My doctor says I am on the right level of medication, so he won't change it. My question is, has anybody found supplements or a specific diet that helps with energy levels alongside the meds. I used to exercise in the gym frequently and find I have no energy for it after working full time, I attempted to push through for a couple of weeks and made myself very ill as a result. 😔
