Confused

My life's always been full of ups and downs. Who's isn't right? Although I feel like these past couple months I have been the verbal and physical punching bag. It didn't matter how I felt or what I deserved. It only matter what was best for some one else. It's always my fault. The depression is seeping into my soul slowly, but surely. I'm losing myself. Or have these experiences only fueled my more. I'm not really sure which way to pu it yet.
