ruled by guilt!

I hate that i am an individual ruled by guilt!  Everyone knows they can convince me to do anything by making me feel guilty.  I live my life full of good intentions that dont always pan out. I try to please those around me and usually i displease myself in the process.  I work so hard to please people and i hardly hear a thanks, but the moment i mess up i hear about it.  I hate that messages are always preached about how we are all sinners and are not perfect.  If this is true than why is it that people expect perfection! if we are told we cant be perfect by the scriptures than why is it constantly demanded from us on a day by day situation?  I have been trying to change and start acting human, but as soon as i do i feel like i am being thrown to the lions... therefore i will eternally be ruled by guilt and strive to be perfect.... and die knowing i strove for perfection!
