My problem with "The Start"...

I don't know how to start this whole MtF thing... like... I dont know how to describe it, but I really do feel like I want to be a woman, but there is always some insecurity about it...

I mean... I've felt like this for 7 years, maybe even more, I even discussed this with psychologist and when I feel like things are moving I take two steps back and I'm at the start again... How can I overcome this?

(sorry for my bad english, I'm not native english speaker)
