Called abut my blood tests today

So the tests for lupus, RA, etc were negative. So apparently my thyroid is causing all this hullabaloo inside me. Part of me is happy, but part of me also knows that sometimes it can take years for things to fully come together for a diagnosis. When I see the doctor, he normally gives me a copy of my results. I just want to see what my levels were. I know borderline can be an issue for many things.
Next, I guess, I will be able to start back on HRT. I'm just worried that I'll have a reaction like I did the last time. If I have another issue again, I was told it could kill me. I need to look up the fillers and dye in Levothyroxine to see if there's any over lap in other thyroid medications.
Since I've been off of the Levo, I've felt pretty crappy. The left side of my neck is in quite a bit of pain and my lymph nodes are a bit swollen in my neck and armpit. The nausea is gone, but it's only because I've basically stopped eating. I have no desire to eat. I just get so sick, but I know eating will help me in the long run, but the pain I get from eating/ drinking anything other than fruit, water, and tea has made me very scared. Other than the constant joint pain, the complete loss of appetite bothers me so much. I wish I knew why I am having this issue now.
