Hey Finally...I know the feeling. I am currently doing Stryde femurs and am about 5 cm into my journey. Might sound crazy but I can say that the month leading up to the surgery was far more difficult than the months after....and trust me the LL process has physically and mentally been one of the most challenging experiences of my life. I'm a highly analytical and neurotic person, on top of that, I kept LL private from my friends and family, so leading up the surgery, I was a mess......depressed, couldn't sleep or eat, couldn't focus on work. I kept going back on forth on the whole thing, questioning the decision, questioning the cost and investment, questioning the health risks, even at times questioning my sanity.
Then, once the surgery happened, and I woke up in that operating room, a weird sense of relief came. It was over with. No more over analyzing, no more questioning, no more living in a complicated mess of a life, it was over and done with. At that point, my purpose was clear and simple.....lengthen, PT, and recover. Trust me that LL is no walk in the park, and I'm still deep in it (5cm on my way to 7 or 8 cm hopefully) but the months leading up to it were far more challenging from a mental perspective. I can say even at 5 cm, as a crippled, with my walk/gait in bad shape, and lonely, it feels worth it standing 2 inches taller on my way to 3 inches. Height dysphoria is a difficult thing, outside of height neurosis my life was great, and I already feel like I'm on my way to getting rid of it.
Try meditation, breathing, anything to avoid over thinking. You'll get through this month and be on your way. The reward is worth it man!
