What's going on

I'm really "madder than a wet hen" now. I sat here for an hour or more writing my feelings out, and my computer decided to mess up yet again and it's all gone...don't feel like it, or remember everything I said.  I don't have anyone around here that I want to bother, or anyone who even seems to care anyway. I hate my job not because of the work involved but because it's killing me mentally and physically. My hands are going numb, tingling and hurting like hell when they regain their feeling, my hips hurt badly, and my back (or kidneys?) hurt so badly,  I couldn't straighten up to button my pants. I gave my whole income tax check, plus my credit card to pay off the hospital bill from January and now the doctor's office wants $840 for the trip to the ER. I was trying to save my near perfect credit from being ruined but, I can't afford this crap. What a wonderful healthcare system we have. If I had nothing, no job, and bad credit, I could've gotten financial assistance. That gives me so much incentitive to try. Thursday, I got up at 4:30Am to shower and get ready to go to work at 6AM. I was there for 1 1/2 hrs. and sent home so I could go back to work another school that night. Someone had called in and I'm a floater so, I get to pick up their slack, no matter what the inconvenience to me. If I don't know in advance, I have to call in most mornings at 7AM to find out when and where I need to go. At that school, I had to clean 18 rooms, 2 multiple stall bathrooms, empty trash, dust mop and wet mop a very long hallway. Friday I got up at 6AM, got ready and called into the office and was told to go to another school at 10AM, then was called back , someone else had called in at another school and to go in at 2PM. I had to clean 20 classrooms, 3 multiple stall bathrooms, and a staff  bathroom, sweep 4 huge stairwells, empty trash, and dust mop 3 hallways. I'm not a "spring chicken" anymore but this is a lot of work for anyone. I take pride in my work and am so devastated by the filth in these schools and a boss that only cares about the shiny floors. He thinks his Thailand girls and African American help is so great. They do little more than empty the trash, and run a dust mop over the center of the rooms! I've seen with my own eyes and heard complaints over and over again from the teachers so, I know it's not my imagination. My vehicles are so old and undependable, I can't go far from my house to another job(if I had one), have no health insurance so, I have to suck it up and suffer. Since Daddy died, my life, my world, and my health have gone straight downhill and sometimes I wish God would let me join them. I can't take much more of this next to non-existent life. I go nowhere, do nothing except clean at home and work, and sleep when I can. I wish I knew or thought that things would get better but what reason do I have to beleive that? Call it self pity or whatever but I know when I've had about all I can take. God, if you can hear me, please intervene. I am so miserable and my outlook on life is very grim. I feel so defeated and alone. This can't be all that life has in store. I wait and wait for a better tomorrow, only to face more disappointment.
