@pianohands123 As others have suggested there are many possibilities for what you are experiencing but have you had your endocrinologist order a new TSH test? It is possible that the dosage you need should be adjusted, and if not enough may possibly cause what you are experiencing. That would be the first thing I would check.
I am on levothyroxine, and anxiety medication. Have had my regular check-up and am in the normal range. I am considering making changes in my career, as stress is a factor. With COVID 19, I pause to make any employment decision, I'm still working and so is my husband. The culture shift that seems to be happening,, creates a level of anxiety of its own. It is uncertain times to be sure. I have seen a therapist, and she doesn't feel my bouts of depression are clinical, more circumstance related. I have decided not to disengage with my family members, because, well, I am all they have, and they won't be on this earth forever. So, maybe I am my own worst enemy. Just trying to cope in these uncertain times. Thank you all for chimming in and offering support. Blessings and good thoughts from me.
