I can't sleep

I can't sleep because of the fear of the things my life has brought me .I can't sleep because the responsibility for caring for another has overwhelmingly drained me . I can't not compare or even come close to a person who dose no wrong. But I feel all of the guilt I say and do things that I know will hurt. The madness and the sadness frightening me like a loud thunder clap .But see all I done your comments you believe you could change me. How about change your self but I can't sleep for the fear of waking up and theirs nothing left .When I know I'm right but give in but is this right .You understand my words when trouble has knocked on your door .Then with out a word you say you was right.
