Am I a bad person if I dont want my kids anymore?

I have 3 children and I find that I cant stand being around them for long anymore. Everything they do just irks the hell outta me. I try and be patient and breathing but I find myself going off on them. And I know its not their fault..and they didnt ask to be here etc, etc. But their dad is being investigated for ually abusing our 2 yo. so the kids cannot be around him ever again alone...and I dont have good family around me that will keep my kids if I wanted to vacation...and my daughter doesnt go to sleep anymore...so I cant get anysleep...and I cant ever find a babysitter, asking any of my family is like pulling teeth...their dad used to keep them while I worked(i worked nights). Im just at the end of my rope....and I dont want them anymore. Isn't it better to like give them away instead of keeping them in a situation that will likely implode?
