Hello. I have had an underactive thyroid for just over a year but still really ill. I take Levothyroxine 100mcg daily. I also have Diabetes type 2 and bipolar illness and clinical depression. I am at my wits end and I am seeing my GP on Tuesday. Can anyone advise me what to say to him, as I get nowhere when I ask for more Thyroid help. Also having my Diabetes reviewed on same day. Any advice please?
