Venting

I just need to vent! I am so fing irritated! I feel bad for feeling this way but err. I need to scream or break something! I am just so frustrated and overwhelmed. My time off from work is spent cleaning what I can while my 8 year old step son goes behind me making a mess! Then I have work. I ask my husband for some time out on a date or something but he is just so beat from work because he feels like we need the extra finances so he picks up side jobs. Because of this and all the kids sporting events and other work he's too tired to do anything nice for us. Then there are my step children whom I love more then life but we get no break while pregnant mom runs with her bf to the movies and all kinds of other thing's having fun and shit while I am taking care of the kids whom never listen. The only away time I get is when I go to my shitty dead end job. Then there is this job. My managers are all cunts! And the policies suck, 24hrs a week is all I am allowed to have ! How is one supposed to live off that? No health care insurance provided! Then my poor husband and kids don't understand why I am irritated and I cant help it! what can I do to stop this irritated feeling?
