I'm sorry you're having a rough time at present. Lots of symptoms, when our dose is lowered due to the blood tests alone, may appear for the first time.
If you have a copy of your latest blood test results with the ranges, can you post them so that members can comment.
There's no history on your profile and I've looked at a couple of past post and you have hashimotos. Did you have your latest blood test at the earliest possible, fast too and leave about 24 hours between your last dose of levo and the blood test?
When your levo is reduced only upon blood test results it can cause more symptoms.
I note you exercise daily and if we aren't on an optimum of thyroid hormones it might be the cause of a reduction of T3 which is the active hormone required. I assume your GP hasn't tested your Free T3 and if you've not been converting levo to sufficient T3 , that might be the reason you feel bad. Ask your doctor if you can have a Free T3 test as that will show whether or not you are converting T4. She may refuse but you can get a Free T3 from a private lab.

Below is a new article published in The Lancet by Advisers to Thyroiduk.
