I think this song is about learning to love yourself and coming to terms with your own flaws and insecurities so that you can love someone else, and find someone who will treat you well. The speaker has had problems with losing her own identity and it seems like she let what the other person/people said influence her way of thinking about herself and things in general and made her hide her true feelings rather than just be open and vulnerable. So now she's learning to be completely herself, realize and accept her insecurities, and "love herself the way I want you to love me."
