Trying to taper.. doctor advice gone wrong

I’ve been on 75mg for 2.5 years now. Before that I was on two different antidepressants for around 6 years altogether also. I want to start tapering off but after talking to my doctor it sounds like he wants to taper me off far too quickly. He suggested alternating 37.5mg and 75mg daily to start with for 2 weeks, then 37.5mg for 2 weeks, then alternating the 37.5mg etc. After reading the guides on here and advice elsewhere I’m really scared to follow this doctor’s advice. Has anyone been through this and found a way to communicate with their doctor? I want to explain that I want to taper a lot slower etc but I’m scared of being “brushed off”. It’s so confusing when the doctors seem to behind on information.
