One handed shooting

Hello all!

Two years ago I survived a stroke and lost my job as a stand-up comedy show photographer as the stroke affected the whole left side of my body my hand especially was affected and I’m unable to use my fingers to focus lenses so I can’t use my camera Rebel T6 at all I’m wondering if there is a way to only use my left hand to focus the lenses and use the shutter at the same time, I looked up shoulder rigs but they seem to be for people with two hands who need to offload the weight of their camera in long shoots
