If you happen to be a vet, you can get one through the VA. My uncle just did. I read your bio. Depending on your financial situation, I would contact social services and ask them for ideas, also contact your area's local Council on Aging as they are a depot of resource information. Blessings and peace to you!
Perhaps your doctor doesn't support you getting an electric wheel chair because you do not medically qualify and/or he believes it would be better for you to use a non-powered chair. Since you list stroke as one of your problems, using your less functional leg to push an non-powered chair would both build muscle strength in that limb as well as build new nerve control paths around the ones damaged by your stroke. At your relatively young age you are a very good candidate to recover enough functionality to be able to walk again, at the least. You will also have more independence pushing a small wheelchair around with your own muscles in your home. My SIL used a wheeled office chair to move around inside her home a lot because it was faster than walking with a cane and she could carry grandchildren (and other stuff like laundry) by sitting it in her lap. Over time, SIL was able to walk better because of the "workouts" her disabled leg got pushing the office chair around.
If you begin using a powered chair for all your movement (including inside your home) you will lose cardiac fitness and suffer permanent disablement, often leading to prolonged depression and an early death.
My SIL eventually got a powered chair to use only when she needed to travel a long distance (like walking through a large flea market) or when she needed to keep up with a group (usually her young grandchildren). She didn't medically qualify for a powered chair, so she purchased one off Craig's list. Powered chairs do have a place in the lives of the mobility challenged. But please consider carefully how much of a place you really want one to take in your life.
