How to taper Nexito20 (psychiatrists

I took ayurvedic meds for severe depression after nexito didn't give any result. Ayurvedic meds made me 90% alright in 4-5 months like many others, I stopped it coz doctor told me u will get alright in 3 months. I continued in small doses. I thought it will not work then I took Nexito20,then flutee60 with side effects which didn't help and I stopped it but after stopping it I had severe anxiety and became much more depressed. I started Nexito20 and ayurvedic again, when I taper Nex15 I become very depressed and anxious. It makes my digestion weak and my condition become worse while taking it. I want to just be on my Ayurvedic meds. Can anyone plz tell me that how can I taper and stop. Should I take flutee20 coz I think it had some adverse reaction on my body when I left it. Plz reply in detail. Parth Nagda sir if u can also. I'm suffering alot.
