I'm getting nervous now...

... as I have an appointment at the doctors tomorrow to see if they can find a reason for the problems I'm having lately. My joints are aching, I'm constantly tired, I have digestive problems, my skin is always itchy, I'm always cold and my hair is becoming quite thin. All of these are symptoms of an under-active thyroid and I'm really hoping it's not that... but the only way to find out is to have a blood test, and I'm petrified of needles - just thinking about it makes me feel shivery and sick.

Fingers crossed that it's nothing serious, I don't want to have to be on medication for life (which would be the case in the case of the under-active thyroid). I guess time will tell.
