What's a good song to dedicate to someone how has done a lot for you?!

So I've been trying to find a song that I could dedicate to my best friend/sister!. I never had a sister, and she's been there for me threw everything, like how every big sister should be!. She doesn't understand how much I appreciate her, even though I tell her so many times!. I want to dedicate a song to her that is guarenteed to make her believe me, and maybe even make her cry!. She's helped me threw everything, when I was feeling like life wasn't worth living anymore, that I wasn't worth anything, when I felt most depressed, and so on!. Some ways she's made me feel in the past, and now, is making me feel that I'm safe, I've never felt safe, but with her, I always feel safe, I always feel like she's there protecting me, she's made me feel like a person with a meaning in life!. She just changed my whole life, and I really want a song, or a few songs that I can dedicate to her!. Thanks for any help!Www@Enter-QA@Com
