As I said, for the most part, altering your ID isn't that important. It is possible that medical insurance through your parents or school may pay most if not all of the cost of the blockers. Don't get panicky yet because there are a number of options to explore first. Do consider ways you can bump up your income because it will get expensive at some point and the more savings you have the better.
I am wondering where the others are because there are people who know how to work the modern system better than me and at some point they should be jumping on this thread with help. The mods haven't even flashed you with the rules yet and normally they are pretty good at that.
