Those 11 months... Are they the prescribed time of living as a female before being allowed surgery? Because even here, where it's state funded and therefore probably not as easy as where you just pay for what you want, my psychiatrist told me there was hardly any problem with doing the surgery after a maybe 6 months if I wanted. Now, the timing is such that the only good moment is after school, next summer, but I think I could have my surgery this winter if not for that. Perhaps some negotiation is possible.
Apart from that, tuck 24/7 and try not to look down too much when showering. Things like that. Or you can distract yourself, so you're less prone to think about your dysphoria. For example by listening to music and singing in the shower. As a bonus it practices your voice.
