What a wonderful trip you made, . It is worth the experience, and the pictures show spectacular places. So if you have the money, traveling is an excellent way to spend it, because it is a gift you give to yourself and the memories last for a lifetime , specially the way you did it, knowing new people, living and eating the way they do in each new country you visited. I hope you can make a new trip soon!
