im truly struggling at the moment. I've been on Citalopram since 2007 of 30mg p/day and sought a therpaist which i'm still seeing. However i've been reducing them over the last 2 years by coming off by 10mg a year. Anyway a month ago i stopped the 10mg dose. Now i'm struggling. I don't think anythings changed in my life, but god it's hard!. So I'm curious to know is there is any physical evidence between underactive thryoid and depression, or is it 'all just in my head'.
