I so understand. I myself wasn't very consistant at one time, but now I have to be or I end up with all the chores. It stinks. I felt guilty too, but if they would listen then there isnt a reason to sound like a broken record. I feel like all I do is correct some kid out of the bunch.
I started something new at our house. Not sure it is right, but we have 7 kids from 16 down to 9, totally old enough to help. Anyway, I wont make dinner until the kitchen is clean. How hard is it to rinse a plate and place it in the dishwasher? They eat and set their plate on the counter, then they are gone which leaves me yelling for the kids to come back and clean up. I now leave everything there and I go on strike until the stuff gets done. No computer, TV or going outside. Mom doesn't make anything in that kitchen until it is clean. Sounds tough, but the stress of constantly raising my voice so I am heard by 7 chattering kids will make me ill.
You are worth more than feeling guilty or hating yourself. It takes a family to make a home work. You can't be a one woman show. I am a bit Obsessive Compulsive Disorder (OCD) and I had to learn it is ok that the dishes aren't loaded right...they got done. I was doing everything because it wasn't done how I thought it should be.
