Kindly suggest alternative medicines.

I am taking desvenlafaxine 50mg, amitriptyline 10mg, clonazapam 0.25mg from last 5 years prescribed by neurologist. I want alternative antidepressants of desvenlafaxine and amitriptyline because these medicines causing extreme hair  loss and also weakening my bone density. I visited few neurologists and psychiatrists but they are unable to prescribe me safer medicines. I don't have any depression or anxiety in real life because i never think negative at all. I have automatic throbbing in head, squeeze like pain in brain, dizziness, migraine with nausea and due to this automatic anxiety attacks come in brain. Whenever I leave these medicines, these dizziness, migraine headache with nausea comes back again. But I want to get rid of these medicines. Please suggest
