Hi Nelly,
Welcome to Heathcare Magic Physician's Desk!
Thyroxine if taken in higher doses for long may be a cause for emotional lability and
palpitation.
You should get a morning empty stomach sample of
Thyroid functions and
lipid profile.
Today's antidepressants are an array of great drugs, you may have side effects to one class but might be totally comfortable and happy with the other so give them a more chance with different version.
Wish you a great health!
