At 16 the feelings you have will remain the same or intensify as you get older. The longer you wait, the more testosterone will change your body and the more difficult and expensive it will be to undo the damage. If you are willing to live with the changes, that is your decision.
In my case, my transition was in my late 20s because it was near impossible to find treatment. I needed 200 hours of hair removal, nose and trach surgery along with gender surgery. My voice couldn't be feminized so I lived with for many years and a year ago I added voice surgery to the collection. I am also 6'2" and early treatment might have cut a few inches off that as some of the hight came after my teens.
At any age, the transition can be difficult. You might lose friends, your choices in life will change and some even have family difficulty. I have suggested to some on the site that they wait until after they complete college and are self supporting before attempting a transition because of family issues.
Make your decision carefully because you are the one who will have to live with it. The transition is possible much later in life but it will become more difficult the older you are.
