I agree with what others have said. If you are absolutely certain you are TS and want to transition, and you have hired her to facilitate and help you with this process, then she should be affirmatively moving in that direction, and not putting up more barriers or telling you you are too young. Now, if you really aren't certain, and she can see that, or if you have some other serious mental health issues that keep you from being able to make a good decision about this at this time, then she should explain that to you, clearly, so you know what's going on, and you can then decide whether her view has some validity, or alternatively, to see someone else to get things going. Don't waste endless time and money with someone who simply thinks transitioning is a bad idea for reasons that have nothing to do with you.
