Tips on cooking?

I’m autistic and I have dyspraxia. I really struggle with coordination, and I also have a fear of knives/sharp things due to an injury I had as a child where I cut my hand open using a fabric rotary cutter. I really want to start helping my partner cook, and I never learned as a child. Are there ways to circumvent using knives, or maybe a technique im missing out on? I always feel like I’m going to cut myself when finly chopping things like vegetables. I appreciate any suggestions!!
