Hi, Calista+12! Yes, I
think there are well-documented interconnections between thyroid problems and depression. You might try searching thyroid/hypothyroid-related sites and information.
The severity of your depression and manifestations such as hearing your father warrant pressing the issue with your caretakers. Remember, those docs are there to serve you, not you to "please" them.
