Hmm, have you heard of learned optimism? The concept cames from the same person (Martin Seligman) who thought of learned helplessness, and basically he's saying if you can learn one, why not learn the other? There is a book http://www.leadershipnow.com/leadershop/1911-2.html and a whole organization that has sprung up around the learned optimism concept, or the Positive Psychology movement http://www.ppc.sas.upenn.edu/

Maybe you will find something useful there. There are also life coaches, who focus on motivating you to succeed rather than dwell on the obstacles. They aren't required to have the training that therapists do, but there are therapists who are life coaches too. You'll find lots of them if you do a search. See what you think.

Wishing you well,
