Hi, leareed. Welcome back to Susan's.
A commonly used resource is the therapist and psychiatrist listing utility at
Psychology Today. It is just one of many.
Here is the link to the main therapist search page.
http://therapists.psychologytoday.com/rms/You can search by state, county, or city, and you can filter for professionals with GLBT experience.
If you have any problems, just post here and I will help you walk through it.
If college is in your present or future, I would strongly urge you to look at the benefits provided by the college and through the student health plans. These could include psychological therapy services and HRT.
