Abm (133111@4)Verse 2(like 1st)

Have you ever felt like giving in
Tried for hours but just can't win
Tell yourself you're not good enough
The struggle alone is just too much
No one's there to hear you scream
You gasp for air but cannot breathe
Did you ever think you'd see the day
When you'd watch your life get washed away
