you didnt list any of your symptoms here
I know I didn't put specific symptoms, I just have so many that some and go and when I read the postings from most of the different topics, many of my symptoms are similar most everyone's - ranging from low and high thyroid symptoms to neurological to lyme. It
I would suggest going to a well trained and certified Chiropractor. They are now a well recognized part of the medical field that can treat many health problems, not just backs. You have an under active thyroid and the flip flopping on symptoms can be due to that. Make sure you are taking your medication at the same time every day. As far as quality of life, ask for some Xanax for anxiety or some other antidepressant. If one doesn't work well after 1 month than ask for a different one. If your depression is your weight and it is due to thyroid problems, it can be lost with extra work. With an under active thyroid you have to work double to lose the weight and it can be done. Take 2 good walks a day. Get yourself some headphones and get out there and walk. Start with a short one and every week increase your distance. I don't know how overweight you are but please don't be embarresed of what people may think. When I see someone overweight out there walking I think "GOOD FOR YOU FOR TRYING". Good luck!!
