Hi there. First, please know that you are not alone in this. The thoughts and emotions can combat each other in your head and really make a mess for you when it starts boiling over. Seeing a therapist is a big help, as I understand how confusing and even frightening things can get.
All of this is good, even feeling confused or scared. This process is far too big to NOT feel this way, so it's absolutely healthy to be where you're at. I'm 30, and have been learning that if I am truly supposed to be Victoria, at any level, then it will not only take time, but will require my not forcing any bit of it in the meantime.
My bit of advice for this post is to find things about yourself that you like or even love, that do not relate to your transition. It could be your humor, or creativity, it could be independence or intelligence. Whatever elements you choose, write them down, or at least keep yourself conscious of them. Transitioning is becoming who you are, matching the pieces you have with what's been missing. Knowing which pieces you already have will not only help you to move forward, but allow you to appreciate every aspect of who you already are.
Much love
Victoria
