I want to turn my life around and become straight, thru the help of
support groups, therapists, prayer and websites.

Without being critical of your decision, I'm going to try to point you
to available resources for "becoming straight." I can't make any
guarantees as to the efficacy of any programs and recommend you
consult more competent authority in lieu of taking my recommendations
as to which information resources to use as advice of any kind. You do
get what you pay for.

I always start with my favorite Internet search engine, Google at:

   ://www.google.com/

Use the following terms to search for relevant resources:

   transformation ministries and gay
   ex-gay
   reparative therapy
   same-sex attachment disorder
   SSAD

Note that you are just as likely to uncover sites that are trying to
counter the arguments of those who posit homosexuality can be cured,
as well as those who propose that such a cure is feasible. This is
unavoidable by the nature of such a controversial issue. For every
"pro" site you find you will find a number of "con" sites refuting the
other.

I recommend starting with The Ex-Gay Nomad who has a pretty thorough
listing of ex-gay groups and resources on a web site at:

   http://members.aol.com/exgaynomad/x_org.htm

This site appears to be a pretty neutral listing of such things, as
well as including links to some counter ex-gay sites (i.e., there are
several links to "Gay affirming" sites and resources). Nonetheless,
for my money (and yours) this would be the best place to start for
coming up with support groups, prayer oriented organizations, and web
sites.

A site that is more aggressively promulgating transformation from gay
to straight is:

   International Healing Foundation
   http://www.gaytostraight.org/html/national.shtml

You are likely to be able to get a list of recommended therapists by
contacting the people at the above site.

Please use the terms for searching Google that I listed at the
beginning of this answer to find even more resources.

Dear earthangel,

I recently spent a lot of time researching this question, although I
must admit I was seeking to educate someone about the degree to which
the vast majority of medical and psychological professionals believes
that 'reparitive' methods and therapies are damaging.

To answer your question, there is only one organization I have found
that specializes in and advocates therapies to "heal" homosexuality. 
NARTH (National Association for Research and Therapy of Homosexuality)
has a site with lots of information you'll likely be interested in.
( http://www.narth.com/ )

With that said, I hope you will research the opposition to this
therapy as well (as we all should when considering controversial
treatments of any kind.) Here are a few sites that might be a good
jumping off point for that research:

"Healing" Homosexuality

Religious Tolerance.org's INTRODUCTION TO REPARATIVE & SIMILAR
THERAPIES
http://www.religioustolerance.org/hom_exod.htm

Jeffry G. Ford (Licensed Psychologist)'as page on Reparative Therapy
http://jgford.homestead.com/

PFLAG (Parents, Families & Friends of Lesbians & Gays)'s page on
Rearative therapy and ex-gay ministries
http://www.pflag.org/about/mission.html

Take care, and I wish you all the very best,
Rebecca
