feelings are fatal

I'm happy for you, I'm smiling for you
 I'd do anything for you, for you
 It's always for you and never for me
 And I need it to stop, so let me tell you, please
 I'm always sad and I'm always lonely
 But I can't tell you that I'm breaking slowly
 Closed doors, locked in, no keys
 Keeping my feelings hidden, there is no ease
 I need it to stop
 And I want to be able to open up, but
 My feelings are fatal
 My feelings are fatal
 How many times must I keep it inside?
 I need to let go and I swear that I've tried
 But opening up means trusting others
 And that's just too much, I don't want to bother
 So I'll keep it inside and I'll bury it deep
 I know it's not healthy, but you won't hear a peep
 Though I'm always sad and I'm always lonely
 I could never tell you that I'm breaking slowly
 Closed doors, locked in, no keys
 Keeping my feelings hidden, there is no ease
 I need it to stop
 And I want to be able to open up, but
 My feelings are fatal, oh-oh, oh-oh-oh
 My feelings are fatal, oh-oh, oh-oh-oh, oh-oh-oh-oh
 My feelings are fatal, oh-oh, oh-oh
