Is there anything I need to do for top surgery?

It really depends on where you are from and what your resources are. Assuming all of the best (supportive guardian, supportive and accessible healthcare system etc)

At 13 you should be able to access puberty blockers which will stop the development in the wrong direction.
At 16 again assuming all the right support you can start taking testosterone.
Then at 18 you could then access top surgery.

Again this assumes all the best. Without a supportive guardian and access to the healthcare on your own there really is not anything that you can do.

 

You most likely will not be able to have top surgery for some time, since you are 13. I also understand that because of your age, there are probably a lot of things out of your control. My advice for something you could do now is to start saving money. It is so expensive, and I thought my insurance would cover it. When they said they weren't going to, I ended up using the $5000 I was saving up for a car and had to scramble to get the rest. Being that top surgery would most likely be at least a few years away for you, my best advice would be to start saving your money for it now.
