@ Missprim Yes, you are on it for life. The thyroxine you are prescribed is to supplement they thyroxine that your body is busy manufacturing via the thyroid gland. And thyroxine in tablet form is exactly the same as the thyroxine your body should be manufacturing.
It really is not a good idea just to stop, you will likely feel worse as a consequence. As a general rule, it is never a good idea just to arbitrarily stop taking prescribed medication, which is usually prescribed to treat a medical condition.
And regarding this point you made ;
" Don't pay for script's but last Wednesday I just decided (on a Whim) to stop putting chemicals down my throat and stopped taking ALL prescribed and over the counter medicines"
I am sure you realise that the water with which you make your tea, or coffee, or the constituents of the potatoes and meat and vegatables that you eat are all actually chemicals? I truly hope you are not planning to stop pouring dihydrogen monoxide down your throat........
