Terry, I'm certainly sorry to hear of your misfortunes.
You'll find that Photography has changed monumentally since your accident.
Film based photography is essentially a dying art, now almost exclusively practiced only by those of us who spent years of our lives learning (and sometimes perfecting) the technical aspect of the process.
Film is OUT -- Digital is IN, which in your case it may be a particularly good thing, because (like Polaroid of old) everything is instantaneous, and thus your short-term memory will be much less of a problem.
I will probably get fried for saying this, but I would suggest that you go with the flow and take up digital photography and forget about (sorry about the pun) conventional photography as you once knew it.
