I think this song is about how you're trying to help a friend with everything you can do, and after a while they start to almost use you. But you're just so caught up in helping them, you don't realize that and that you hate what you're doing. When you realize it, you just need a moment to yourself, and "hide yourself away". But then you find out that your friend sincerely needs your help, and when you're calmed down, you decide to help them one last time.
