The doctors told me the reason I can’t walk much is because I have weak lung power.

It’s NOT lung power. It’s endurance.

So what if I get short of breath when I start walking? Everyone gets short of breath when they start jogging. That’s what I’m comparing walking to: jogging. Right now, walking feels like jogging. Your heart beats louder, you get short of breath, and you want to stop. The only difference is my heart rate doesn’t increase.

Before transplant I felt the same thing while running that I’m feeling now while walking. Before transplant, when I ran, my heart beats louder, and I got SUPER short of breath. In fact, I got so out of breath and my heart beat so loud I had to stop. It’s the same thing now (well, actually it’s a milder version), only that now it’s walking. See? It’s about endurance. If I had more endurance I’d still be feeling short of breath, but only during exercise.
