I would re measure yourself in the morning. use a wall scale at the doctors.
aim for (6cm on tibia) and (6cm on femur), do monorail external for both.
this is both affordable and doable if you choose a good doctor.
you will be approximately 5"7(close to 170cm) after the first surgery. this is a great height, where you will not be considered short but will be in the category of if only you were taller, after your second surgery you will be approximately 5"9.5(you will be 175cm which is really close) basically average height.
at average height your life will change drastically girls will no longer criticize you for your height or even care, sure you wont get bonus points for being tall but all the negative points will be gone, the discrimination will finally be gone.
LL is suppose to be an improvement. I know your feeling down at the moment, but trust me get the height increase to average, and then if you still feel like crap you can kill yourself then lol jokes, but in all honesty trust me you will love your life at average height, and you can still wear lifts if you want that extra boost. you owe it to yourself to at least see how awesome life is at 175cm
don't focus on a number focus on an improvement.
