How to deal with Buzz?

My owner, Andy, I am Andy's favorite toy since he was in kindergarten. I live in Andy's room with my friends as his toys. Yesterday, my owner, Andy had a birthday party at one week before his family will move to their new house. My friends and I found out Andy received some gifts for his birthday by using the baby monitor. Andy and his friends left his room after he put his a new toy named Buzz Lightyear on his bed. When my friends and I met Buzz, Buzz thinks he's a real space ranger that he doesn't know he's a toy. After Andy's party was over, he put all bedsheets, drawings and posters with Buzz replaced me as Andy's new favorite toy. When I found out Buzz became Andy's new favorite toy, I became so upset because I am Andy's favorite toy all the time. I tried to get rid of Buzz but I couldn't do because Andy wanted to play with him. I also tried to telling Buzz that he was a toy but he didn't listen to me that he thought was a space ranger. Now, he is getting on my nerves! I want Andy back me as favorite toy again that let me know how can I accept Andy pick Buzz over me if it doesn't back me as favorite toy again instead of trying to get rid of Buzz that it will make Andy feel very sad?
