I found these two boards....can't vouch for them, but both links worked.
HealthBoards.com: Spinal Cord Disorders Message Board, they also have a board for depression.

Braintalk Communities: - has both a forum on spinal injuries and one on the psychology of chronic illness...not sure if either of these will help
