"Wraith" by BitBard (bitbard@newsguy.com).

Gail is a young blind woman who has lived a miserable existence under her bitchy aunt's supervision while working at a telemarketing job that she despised. Then she finds herself in touch with a mysterious spirit, who gives her feelings that let her feel good about herself. Exactly how this leads to sexual and emotional fulfillment I'll let you discover for yourself.

It was a very good story. Even if you don't believe in ghosts.
