Josh,
Worth it! Worth it! Worth it! The last 5 years of my life has been absolutely amazing. I can do things now that I have never been able to do before. I am able to work hard, play hard, and take care of myself every day with great results. I'm in the gym everyday, I'm strong, and I'm just as healthy as any other 26 year old out there. I just ran a half marathon in the spring too (13.1 Miles!!).
And yes, there are bumps in the road. Meds, Colds, being careful, and most recently for me, PTLD. But even with all of that, my life now is still 1,000,000,000,000 times better than it was before. I was confined to an apartment. On oxygen. Had very little to no social life. Couldn't go to school anymore. Life was just so difficult. And while you will experience things post transplant that disrupt your life, it's very very well worth it.
Good luck!
