I want to go for gender transition (m2f

I am 28,M. Since young age, probably after my teens, I have this thought of seeing myself as woman though I am a man. I always attracted to woman, but more than i always want to see myself as the other girls. I like to dress too, but never dared. I can't see my self in a gay relationship but i might want to be a guy as a woman.i don't have much female traits except the desire to be  Since past 2 thought have become stronger day by day and became the urges. I don't know how the past year passed, i was depressed ama confused about gender identity and sexuality. I wish I could change sooner but something stopping me. I am doubtfull and confused all the time. All day long, one thing that goes on my mind at any given point of time is that I want to change. I know it's irreversible. But i don't want to continue being male. I wish I could start hormones early. I wish I got guidance. Please advise. Thank you
