Hi Mac,
Just caught up with your post again today, I know how you feel but things will get better,I know you can't imagine it at the moment,but trust me they will.
I have looked at over symptoms of to much thyroxine, and yes one is loose stools and anxiety, adrenaline surges etc. When that's settle down you will be able to re-start your HRT , as for which HRT you take is down to personal choice,and if it doesn't suit you after 3 months you can change to another.
I personally am on Everol sequel 50 mg patches these were chosen by my gp as I suffer from silent migraines and patches don't go through your stomach, but by pass it so cause less problems with headache/migraine and upset stomaches if that may apply to you. Mine have so far Been brilliant,
I get a 3/4 day fairly light bleed onweek 3 of the mix patch oestrogen/progesterone .
But saying that I've been taking the thyroid med for 6 days and my period has not arrived, although I have stomach cramps so maybe it is them causing it.
I would definatley hang in there a bit when you start the HRT again as the improvements are well worth waiting for my aniexty went after about 2 weeks together with flushes and sad feelings tougher with the tears.
I still feel quite ill after doing anything for more than 1/2 hour or so and my mouth really starts to tingle, can you remember how long after you first started your thyroxin you started to feel good again.
I hope you start to feel better soon.
