Welcome, Kimberly.
Here is a link to our known list of gender counselors/therapists. You want a counselor that already knows transsexuals and the WPATH Standards of Care. <

Seeing a counselor on a monthly basis should help you both to determine whether or not you truly are TS within 3 or 4 visits. Three months is the minimum requirement for a counselor to write an authorization letter for hormone therapy.
With your letter in hand, you can then search for a doctor willing to prescribe hormones. That can be a real challenge in some locales. Your counselor should know with whom you can work.
I began my transition in the Seattle area when I was 61 and began HRT (an anti-androgen and a conjugated estrogen) after about 7 months. Had SRS on my 63rd birthday. I reduced my estrogen dosage when I turned 70 (we don't discuss dosage numbers here) and now take my estradiol sublingually, which reduces the amount of liver exposure. I have my liver enzyme levels checked annually. I began HRT with a VA endocrinologist, then my Naval Hospital primary care physician, and now my Medicare doctor.
If you are over age 50, check this link, too. <

So, find yourself an experienced gender counselor and check in here frequently.
Enjoy the journey and Rush Slowly.
