Tiffany,
We all know what a hard journey is this and we are here to hold your hand. The first time I made the therapist appointment I was really fearful. I couldn't believe I was actually doing this. Then when I went in her office I unpacked so much and I did firm up the decision to transition. Some people don't and that's fine too. Seeing a therapist is a good way to help you decide what you want out of all of this.
Remember as well that everything is on your own pace but you're not going to make an omelette without breaking a few eggs. I don't mean to scare you but you will have to be brave and strong throughout this. Don't feel pressured though, but it will often take a leap of faith for things like going out in public. There may be negative and there may be positive. However anytime you need a shoulder to cry on, you can reach out.
I am a parent, career woman, engineer. All of our experiences are different:
Good luck!
Much love
Kate
