Feeling so overwhelmed

It seems like nothing ever goes "my way".My girls are at each other's throats and I've got to have sleep before work tonight.The house is a neverending nightmare and just never seems to get better.K won't help for weeks stating that he did this or that....No shit,that was weeks ago....I've tried strikes,threats and all out war to no avail....He is caustic and hateful to everyone in the house anyway and I just don't know how much more I can handle....Sometimes I just want to run and hide....My girls are my life though and I could never do that....I try so hard to make everyone happy and live in harmony and still things unravel at every turn....I feel like God must really hate me sometimes....I'm in such a deep depression right now that I am afraid of losing my job or worse....I can't concentrate on anything....I so wish I was financially capable of supporting my self and my girls,but that will never happen....{sob},I'm doomed to this life....All I can hope is that K and his mother don't cause permanent scars to the children....I so despise that woman and what she has turned her sons into....I have no idea why I am still with him other than the fact that I would fall flat on my face without his paycheck....Sad that is the reason I chose to stay in this....I'm sure there is more....There has to be....Dinner is waiting.....
