How Can A Thyroid Goiter Be Identified?

I went to a doctor who said I have a goiter and ran a blood test. The results won t be back for a few days. I have been sleeping way too much for several years (had been attributing this to something else), gained weight and lost interest in many things. I often can t get out of bed for important events. My boyfriend s is at his wit s end and doesn t feel my condition warrants such extreme conditions, feels I must push myself. I understand his frustration, but can t help it until this is treated. He also has hypothyroidism, but never had such severe symptoms. I read a lot and understand the condition, but just can t get him to understand this and it s really hurting us. Please help me get him to realize it s beyond my control.
