Could the doctor have missed something?

I am a teenage girl I don't know if this will help but I just thought I'd mention it. I went to the doctor about a month ago for persistent symptoms. I had my parents ask for a blood test to check for thyroid problems. the doctor said my levels were high (I forget what he called it) and he scheduled an appointment with a Endocrinologist. she felt around and said my thyroid was enlarged. she ordered another blood test. I had to wait a week still having to deal with the symptoms and go to school miserable. she called back and said my levels were NORMAL. I am at my wits end I don't know what to do and my parents don't know what to do either. should I go back to the doctor and ask for something more complex to test for thyroid problems?. I seem to be getting new symptoms every few days as if whatever it is is getting worse the strangest thing is some days I can feel good and the next day I don't want to get out of bed. just like today it was warm (its winter where I live) and I went outside to enjoy the warmth. I was out maybe an our and had to come back in. My symptoms are worse at night and evening hours. Here are my symptoms:
fatigue
weight gain
sometimes when I swallow I get choked because of something swollen in my throat
headaches that disappear and come back
tonight I think I might have a slight fever
dry skin
hair falls out
mild depression
irregular periods (I was expecting my period over a week ago)
nausea
trouble concentrating/trouble remembering things
my joints ache
acid reflux
stomach upset (this is becoming less frequent though)
One day I can feel like I can't get enough to eat and the next day I don't want to look at food
I had a stomach virus that took me over a week to even feel better
Sometimes my throat feels like it is very small and I have trouble breathing because of it
I wake up at night a lot
I get hot/cold easily
My voice is all out of whack if you know what I mean
I seem to have less muscle strength in my legs

The endocrinologist thought I might of had Hashimoto's Disease.
What should I do now? My symptoms are getting harder to deal with. Thank you very much

They probably missed something.
Go back and say 'I've got all these symptoms and you seem to think I'm fine. please re-do everything.'

I have about half the symptoms as you, and I thought that it was totally normal.

Normal levels are based on a health 20-25 year old white male. all lab values are based on this. So just because the doctor says you're in the normal range you can still have something wrong with you. only you know your body and what's not normal for you! also, do some research on Hyperparathyroidism and Hypoparathyroidism. it looks like your systoms may match one or the other. (can't tell which one).
