Mistaken 가사

There's no joy without the pain it's the pain that makes us strong but sometimes it's just so hard to carry on when you said that you don't care when you said that you'd be there well i wonder just how did things go so wrong with everything we had and you know it's just so sad but who's to blame do who are you i thought i knew i guess i was mistaken so say goodbye don't tell me why i guess i was mistaken i know i can't run to you again cuz you would only run away i guess there's nothing i can do to make you stay you said that you would never leave a lie you told and i believed and now you wanna go and throw this all away so what is happening here it's exactly as i feared your just the same so who are you i thought i knew i guess i was mistaken so say goodbye don't tell me why i guess i was mistaken as i blame myself again wondering what i did you tell me that you still might care for me you say that your confused but thats really no excuse you don't get sympathy cuz i don't need this mind trip i must be myself must free myself from you and all you put me through so who are you i thought i knew i guess i was mistaken so say goodbye don't tell me why i guess i was mistaken cuz i only wanted you
