Dave;
one of the great things about Vocational Rehabilitation is that it is a program designed to deal with the disabling condition first. It's about so much more than the vocational retraining. A good counselor would work with you, assist with getting you to a therapist if needed, psychiatrist etc, etc. then when you were more stable, vocational retraining could be the icing on the cake. Hope things work out well for you.

Though inland far we be,
Our souls have sight of that immortal sea
Which brought us hither.
William Wordsworth (1770–1850)
