Welcome to our forum and I notice you joined in October 2016
It's now time to take your own health into your own hands.
First, make a new appointment to have a blood test for TSH, T4, T3, Free T4, Free T3 and thyroid antibodies. Also B12, Vit D, iron, ferritin and folate. (we can be deficient which cause symptoms too).
The appointment has to be the very earliest and fasting (you can drink water) and allow a gap of 24 hours between your last dose of levo and the test.
Get a print-out from the surgery. You have to request it and we are entitled to a copy by Law. You can tell the doctor you are now going to get a copy after each blood test. Make sure the ranges are quoted. We cannot comment on results without the ranges (labs differ). My surgery charges 30p.
You can tell your doctor due to your age of 42, that you have no life and have severe symptoms which you are getting no relief from and tick off the ones you have and you can show him. Tell him also you've taken advice from the NHS Choices for help/advice on dysfunctions of the thyroid gland.
The aim of taking thyroid hormone replacements is to get our health back with relief of all symptoms but we need an optimum and not have dose stopped due to the TSH alone.
