I'm not sure what you are asking here. Obviously the topic is how Frodo changed from when he was in the Shire (the beginning of Fellowship) to when he went back to the Shire (the end of Return). Well since you didn't ask any specific questions, I'll just give you some feed-back. I believe most of this change was due to the toil and hardship that Frodo went through on his journy. He went through so much pain that once he got back to the Shire, he still felt that pain. That is why he left. Or most of the resson.
