Firstly, it was very rude and ill-informed of your doctor to give you antidepressants! quite a lazy thing to do, frankly.
It seems to me like a jaw or jaw alignment issue. Have you injured your face or jaw recently? I remember having something similar once after a bad bout of cold and flu, made me think something is wrong with my entire jaw, causing my ears to crackle.
Wish you the best and hope this helps
