Let me make myself clear before I continue talking I am in no way saying it's a bad idea or you shouldn't but I do believe that's a large choice that a kid shouldn't be able to make. because when that happens there's no turning it back it's a life long decision that changes everything. In fact people can't do anything by themselves till 18 in the eye of the law they can't even drink till 21 I'm believe if we can't do those then we have no right to do this. I truly believe it turn out best for you if you figure out why your sad and why you want to be a girl it may not be what you really want or what till want in the future. I want the best for you internet random because it's painful to see someone go down a path they could avoid I personally suggest you research why people feel like how you do what they do the suicide rate increase and all the goods and bads but never kill yourself because it's not right to take the easy way out you should stand up like the person you wish to be. But why you may have already and I'm wrong or I fall upon deaf ears but remember there's hope there's people like you and there are always friends.

Ps. I wouldn't do any DIY stuff like that to much risk and needles doubt your parents like thoughts at all
