I received a call from my doctor today ! It appears because of the rotten disease it has affected my thyroid. That would account for the fact I have gained weight had really low mood and feeling cold all the time.
I knew something was wrong have felt rotten for a while now. So here we go with more medication. Doctor says it will be three to six months before I see a difference.
Thanks to everyone who replied to my post yesterday. I really value the support I receive on this site.
