Best ways to volunteer with potential to get a job if you're in a wheelchair and have cerebral palsy?

For a while now I've been out of college. I am 21 years old. I have cerebral palsy which causes me to be in a motorized wheelchair now I plan on going back to school. I would like to become an editor of some sort, whether you movies or commercials. I also love writing as well. So I was thinking about doing a little journalism but right now I'm looking for places to volunteer with the potential for job I have not worked at all before so I am extremely nervous and I know the timing bad. So everybody's looking for work. I just feel as though I've been struggling to find a good direction for my life. I feel I'm a very intelligent person. I just have some difficulties in have to do things differently. So if anyone can help me at all. I would be extremely grateful for your time. Ahank you, Alissa
