Where is me????

I feel lately I left who I know as me for something that I feels makes me a weaker person because I am wanting to please everyone else. But where is my fire inside to say no and not to cave into anything. I want the old me back I want to feel that I am a free bird once again, but I don't know how without hurting feelings just a little and causing fight. Where is my F**k you attitude and why can't I stop caving in.
