Have been through hell over last 2 years because of my stinking thyroid!

I am a successfully (or so I thought!) treated bipolar sufferer on lithium for 10 years however it now seems that the lithium may have caused severe recurring thyroiditis. Dealing with sceptical endocrinologists has been soul destroying. The symptoms have been torturous and my last consultant blindly increased my lithium inducing a serious lithium toxicity.
The problems are that recurring thyroiditis is rare and consultants are reluctant to remove my thyroid despite positive scans and bloods because thyroiditis (not recurring) should be a temporary condition.
Anyone else had a similar experience?
Desperatly seeking a thyroidectomy! stopping lithium has been deemed not an option.
