A couple of years back, I had blood tests and everything came back 'fine' , except for a vitamin D deficiency, which was treated with supplements.
But I really think something is amiss, mainly with my thyroid. These are all the symptoms I have, which all came on around the same time.
-diffuse hair loss (diagnosed as female pattern baldness at 21 years old)
-ridged fingernails, which flake off and bend very easily.
-insomnia, followed by really vivid nightmares when I do fall asleep.
-waking up with horrible migraines.
-loss of appetite. (I forget to eat sometimes if DP is away, I just don't feel hungry at all)
-anxiety and depression.
-brain fog. Just yesteday, DP's mum came to visit, and she was talking to me but I just zoned out. I was trying to listen but it was like nothing was going in, and I honestly couldn't tell you a single sentence she said to me 
-freezing cold hands all the time, even in summer. They really are like ice blocks & people jump when I touch them.
-my skin has a weird yellow tint to it, and has gone really pale.
-moon face. I'm slim, but my face, mainly the jaw, has expanded so wide that I don't look like the same person anymore, and it feels hard rather than fatty.
-thinning brows, lashes and pubic hair. (Googling seems to suggest there are no links between this kind of hair loss and female pattern baldness.)
-bad acne, all over my back, face, chest, upper arms.
-excruciating period pain that travels down the front of my thighs and up my back.
When I had the blood test, the Dr just told me everything was normal and I didn't ask specifics, but I know that different doctors have different ideas of the ideal ranges. Would I be unreasonable to ask for them to dig deeper? I don't want to be a pain in the arse, but you know when you just know that something's wrong?
Just looking for opinions, I suppose, on whether you'd be concerned? Would you go back and ask for more help? I think my anxiety is holding me back, because I don't want to come across to them like I'm telling them they're wrong...
