anxiety
"I developed anxiety attacks, as many do after a Total Thyroidectomy.  I suffered for a year with inadequate thyroid treatment and all the awful things that come with it. Then developed panic/anxiety attacks.  They would last 6 or 7 hours at a time.  I would barely feel better and then I got another. Ativan helped in 15 minutes. I've been taking it for two months and it has given me back the small part left of my post-thyroid life. Thanks to my thyroidectomy, I will never be well again.  But at least I don't have panic attacks."
