Hate the health care system.. Sorry for the long post

I myself work in the health care system and now I can see my patients frustration when it comes to their doctors not understand when they tell them there's something wrong. For the past couple of months I have been experiencing thyroid symptoms. The works; extreme fatigue, irregular periods, memory loss, hair loss and a few other things. I went to my gyno mainly for my irregular periods so she ordered a series of blood tests. Mostly hormonal blood tests and also a thyroid stimulating test. The thyroid test came back low in which case they told me to follow up with my primary, which I did. My primary then ordered a tsh again along with a free t4 and a t3 uptake and an ultra sound of my thyroid. The tsh and the t4 came back with within range but low and the t3 came back low and out of range. The thyroid ultra sound showed that I had two swollen lymph nodes under my thyroid. So my primary explained to me that she was going to put me on antibiotics for and infection (that I honestly don't even think I have) and have me get a complete blood count done to see if my white count is elevated. On top of that she ordered a cat scan for my thyroid, that's it? I'm just very discouraged. I feel as though she's not doing everything she could and it quite frankly pisses me off that she would think all my symptoms are related to an infection when all my blood tests prove that there's something wrong with my thyroid. While I'm only a phlebotomist and not a nurse I do know things about health and I do know that there is more tests related to the thyroid that she could be doing. Being tired every single day is a constant burden and I don't think a lot of people realize how much it effects a persons life. It effects everything in my life; my ambition to go to work or do anything for that matter, my relationships with my boyfriend and people in my life, my tasks that I should be completing, my ability to drive is even effected as I constantly have to fight the urge to fall asleep. I choose to sleep over all these things. Sleeping is my favorite thing to do and it's what I constantly think of. Then when I tell her this she tries to push depression medication on me. I kind of want to switch doctors but I know it could take weeks even months to get in somewhere else. I just feel so help less and all I can do is cry.
