Cannot comment on thyroid function, but I am diabetic. Diabetes can lead to high cholesterol levels and high bp,. Your bp is elevated for diabetic, wanna keep it below 140/80, this is range at my diabetic clinic.
Diabetes can contribute to weakness/lethargy, and cause frequent urination/thirst. Get diabetes under control, these symptoms will resolve.
Thyroid/diabetes have similar symptoms, so testing would be best way to confirm any disorder/treatment. Wishing you well.
Everything you listed can be effected by T3. The thyroid controls SO much in our body. If one thing is off it has a huge affect. I think the worst for was the palpitations and anxiety. Just keep telling yourself "it's all fixable" and you will be OK. Best of luck..
