Hi Kara,
Well you certainly are starting out with a tough question here. It's not that the question is so tough, as it is that there are probably going to be many answers.
I understand you not wanting to waste time being evaluated, but evaluation isn't a bad thing. It gives you some time to consider whether or not HRT is definitely the way to go for you. And you also get to discuss the upside and the downside (if there is one for you) of taking medications.
Personally, I went through the evaluation and decided that if the treatment is right for me, it just isn't right for me at this time. So, the evaluation will help you decide if this is your time or if it isn't. It gives you time to think about what your goals are long term and short term. You can decide if your ducks are all in a row. And, if you see an evaluator who is experienced, you can share the process with your current therapist. This will help you both out.
Some people do not need the evaluation because they are certain and their circumstances allow for them to just go for it.
In my case, I was going to a clinic for Gays, Lesbians, and Transgendered people. They decided that I was emotionally able to handle the HRT and they approved me for it. I never did see an endo. Some people will advise you, however, that a good endo is a must because that doctor can help you with getting the doses you need for maximum effect for your particular body.
So, to summarize. I say go for the evaluation and think of it as a learning experience. If your present therapist can't suggest the right steps for you to start HRT, then the evaluator may be able to help you with working out the best course of action in terms of what kind of doctor to see and maybe even give you some names.
I hope things go well for you. Do not allow yourself to get depressed or anxious if you feel that things are not going fast enough for you. The important thing is to know who are are, what you want, and how to go about getting it done.
I wish you well,
Love,
Rebecca
