my life sucks and so does my job

why do i do this job why do i come to work everyday to take care of people who dont give a crap that we are there for them most of the time.....i have destroyed my back, my body and my mind for this job for crap money to come to work and get crapped on by the people i work with  to get crapped on by the patients and there families.  i understand this is the worst time for people in their life when we come into there home and i am very very compasionate with my patients and there families.  i just would like a little respect from the comunity............it may not seem like it but i risk my life for 12-14 dollars an hour depending on what position i am working so my life is worth such a miniscuel amount it is rediculous....i know i chose this job but alot of people cant do this job cant carry around the horrible things you see that stay with you your whole life....like the person you knew that just shot themselfs or working your own mom when she goes into cardiac arrest or the faces of the distraught families......those stay with you they dont go away you carry them in your soul till a person dies then i imagine i will be in some sort of hell when i die with all this horribleness i have lived through.....there have been many times on the job where i should have been killed and i just got lucky i guess situations that were very bad i dont know sorry for the rant i am just fed up no respect anywhere
