I find it hard to trust not only me, but everyone around me

Because of you, I never stray too far from the sidewalk
Because of you, I learned to play on the safe side so I don't get hurt
Because of you, I tried my hardest just to forget everything
Because of you, I don't know how to let anyone else in
Because of you, I'm ashamed of my life because it's empty
Because of you, I find it hard to trust not only me, but everyone around me
Because of you, I am afraid
