Good Morning!
First, I am not a clinician or physician. However, I suffered from undiagnosed thyroid disorder for most of my life. It all came to a screeching halt when anxiety grew into panic attacks & escalated even further when I was prescribed "Ativan" & a low dose thyroid medication.
Landed me in the hospital. It was a blessing for me.
What I have learned through this experience...kinda like the chicken & the egg story. Which came first in my case. Depression suppresses the thyroid gland. A lack of balance with the thyroid causes depression.
Your thyroid has a great deal to do with all of your other organs & their optimum or lack thereof regarding performance.
Have a heart to heart with yourself first. Make a small change every week & make it "stick." Diet, exercise, break your routine, keep a journal. Particularly at this time of year food banks are desperate for volunteers. A few hours a week could be of tremendous help to Salvation Army.
See if this helps...even a little with your mood. Look to improve your own life with clarity & forethought. Give it 30 days.
Go back to your primary care physician & request another battery of tests. Request your psychiatrist either write a letter and?or call your medical doc. Get support.
I wish you well. You are ahead of most young people...you are asking questions! Keep it up. YOU are your own BEST advocate.
kindest regards,

woops meant to type FT4, not FT$
Your doctor should also be testing FT3. T3 is the "active" form of the thyroid hormones, the only form your cells can use, so FT3 level is very important.
If I were you, I'd ask my doctor for a trial dose of thyroid meds to see if it helps your depression...bet it would.
