I'M TIRED OF IT ALL!!!!!!

Something about today that just isn't right. Or maybe it has just been this way all along. I always need help with my babies and last night I needed help to get them to bed, put them to sleep and keep the house clean. I'm the one that always ends up doing everything. I leave the dishes for days on end to see if the husband would wash them, but he don't. I leave the clothes piled up to see if he would wash them. Yes, he would only wash his clothes and the leave the rest for me. We've had this talk and this argument before, several times even. I'm sick of it!!!!!!!!!!! I'm tired of trying to raise my kids by myself and having people tell me how to raise them or their babysitters not wanting to watch them anymore.
I'm TIRED of my so called friends and relatives only needing me when they mess up or when they need someone to dish out their bullshit on. I've extended my hand out to a cousin that has been raped and took time away from my job and mu kids to try and help this one. But all she wants to do is lie to me and keep me waiting for her. I love her but I am not going to put my life on hold to be there for her if she doesn't want it. I just can't do it no more. I have people that need me and need my time.
Then having a supervisor that wants to come at me for shit that I didn't do wrong. But I took it and made something up to cover for it. I guess I can't go to lunch and be a couple minutes late to work. But yet I cover for her all the time and she can up and leave, make all these mistakes and expect me to fix it all for her.
There's so much things in my life that just have me wanting a way out. Is there some way that I could take my children and I away!!!!!! I'm so sick of the way things are going. I'm ready to just give in and lose the battle. I'm sick of being the one carrying the weight of the world on my shoulders and having to act like I don't feel shit..........
