Is it normal to get so stressed over nasty children?

My partner has 3 daughters 9, 12 & 14yrs old. I wanted to kill them, I am now on anti depressants because I nearly killed myself for thinking the way I did about them.Is it normal to sink into a dark hole?
They are so nice to me infront of their father but behind his back they are little bitches to me. He can not see half of what they do to me, I have tried to love them but it seems that they are not open to my love! I try to talk with them and all I get is the occasional grunt and shrug.
They make me out as delusional, like they are innocent and have no idea why I am upset. When they do get caught out for lying, he forgives them because they put the tears on and make up outrageous stories between them that he just has to agree to what they tell him and he brushes it off. I can not get past the past and move onto the future like he does. I get sniggers when they ruin any plans we have, they can go days without talking to me unless their father is around. I love my partner and he absolutely love & adores me, I know it is hard for him to be in the middle. I want to walk away from all the drama that makes me sick with stress but I wouldn't survive without him.... what can I do to stay sane and not burst out with rage at Daddy's little gems? He want us to live together and I would in a heartbeat if I knew how to handle them. I am a mother of two teenage boys, 16 & 22, that are so happy, polite, loving and caring, well educated and well adjusted. So I know my parenting skills are above average. My boys love my partner to bits and vice versa.
Am I normal to be so sick in the head and want to play vicious games back? help me!

    O trust me they know what their doing and their doing it just to get under your skin. Sounds like their the ones smarter then you! get control of yourself. They wonna see you break down its only normal for kids to hate step-parents. It happens alot. Seek help for yourself before you do something stupid!

    Sounds like normal kid behavior. Don't let the mind of a child outwit the mind of an adult.

    I cannot relate much to your problem, but they sound horrible. You are probably smarter than they are, so maybe try outwitting them? I really do not know...

    Thankyou for your support, I have been beside myself over it for a long time. You are right I am Older and Wiser! I just needed someone elses opinion, I do see a counsellor once a week but she can only listen and give me the tools to control my emotions... I don't get any advice on how to deal with them.
