Hi Dawntreader & darkeyes,
Gosh you guys seem to be so much more informed about your thyroid difficulties than me. I have Hashimoto's disease- dx- at 28 years old- so I've had it for 14 years now. I'm not aware of some of what you're talking about- except the correlation of low-thyroid and depression.
In March of 2000 I decided I probably didn't need to take synthroid anymore (I believed the doctors had made up my problem and I really didn't have it) and I hated having to have my blood levels checked every year- so I, myself- went off the med. At that time I never heard of low-thyroid being connected with depression. I was off of medication for 3 months then had an appointment with my physician for blood work- a few days later, he called me and I went to his office. I didn't tell him ahead of time I quit taking the meds but he saw the test results. He asked me "What's going on?"- then I told him I quit taking synthroid. He got very angry at me and said that my body can't be without this medication, and that my levels were off the charts.
Boy!! Six months later I was diagnosed with clinical depression and have been batteling with it ever since.-- A connection?? I'm thinking there must be something here -- with thyroid and moods.
I do have other issues like PTSD-from childhood and various other personality disorders- which probably also contributed to the depression- but I often wonder if the low thyroid was the thing that put me over?? Gee,

hope you don't mind my rambling on!!.....
Anyway, dawntreader- Sorry I don't have any suggestions, I just wanted to say that I can understand your struggle. Hope it levels out for you soon! Good luck!
