Have had hypothyroid for at least 7 years, formal diagnosis for 2 . Have recently had increase in TSH,which on reflection has been cooking for at least four months. Heres my problem ; three weeks ago had a major melt down and amongst a whole host of other symptoms have crippling anxiety to the point of being signed off work. In and out of GP surgery meds upped again (levothyroxin) but cannot get my reluctant GP to confirm the link between thyroid and anxiety. Have had no major life changes or undue stress. I know hyperthyroid and anxiety go hand in hand but can anyone tell me if this is also the case with underactive thyroid?
