I Need to be useful again

In 2005 I sustained of a freak fall in my bathroom doorway. Before that fall I was employed, I was active in volunteer work, teaching reading, and in several groups. I lived a vibrant colorful life. Now I am confined to a wheelchair since shattering my thigh and shoulder. I have been fighting for state sponsored transportation since then but keep being denied because I am in an electric wheelchair. I am unable to use a manual wheelchair due to my injuries. Since being forced to stay at home I have become depressed and have lost my lust for life. I used to help others and now I can barely help myself. With a wheelchair van I could continue my volunteer work, get a job, and enjoy social outlets. All this would improve my health dramatically returning me to a vibrant contributor to the world instead of ne who is only a drain on society. I want to be active again. I want to be able to do for others. I want to have a life besides staring at 4 walls and watching my brain turn to mush. Please help me.
