Sorry it didn't go as well as you'd hoped. But you did it, you made it home, and you've learned what not to do next time. That's one of the things I love about touring, it always teaches me something. I was way too aggressive on my first tour as well, and paid for it with six months off the bike waiting for my knees to recover. Not good. But I learned, boy did I learn.
Hope the next one goes much better.
