I Am A 21year Old Student, And Have Been Extremely

I am a 21year old student, and have been extremely tired, since March, my jaw clicks out of place and it hurts when I yawn and chew it has been like this since December. I have had anxiety and get very irritable. My body aches and my neck and shoulder muscles are sore. I have been for physio, but still struggle with this. I have mild hyperthyroid and slightly low iron. Although I have started taking vitamin and iron supplements my symptoms have deteriorated.
