Please please please help me part 3

I keep losing what I'm writing and the screen keeps moving up so I can't see what I'm writing.

I can't remember what I wrote before it was deleted.

Basically I'm scared someone will see how bad it is here and call Child Protective Services or something. I can't lose my girls. I love them more than anything but even that isn't enough to make me clean the house up.
A friend offered to help me but I don't want her to see how bad it is so I said no.
It's overwhelming. There's just too much of it. I want to do it. It's like I just physically can't.
I always thought having OCD meant your house would be spotless all the time. But even though I have a fear of germs I cannot do it. It's that fear of germs that makes it worse - I'm scared to clean incase I get something or find something like roaches. I'm scared of bugs esp. spiders, maggots, roaches.
My husband wants to help but he's working full time and he doesn't have the energy when he comes home plus in the weekends we usually have other things to do eg the grocery shopping and normal housework eg washing so we have no more time than during the week. Plus the kids get in the way and it's hard to leave them unsupervised because they get into trouble eg my 4 year old just scratched our new LCD TV screen on Tuesday morning when I was showering. We can't take our eyes off them. And my mum won't babysit both of them at the same time... says it's too hard. So there will always be one of them here. Plus they rarely wan't to babysit. I don't know what to do. I want to get help. We can't keep living like this. I think I will end up killing myself because it depresses me so much and I can't live a normal life. I don't want to get close to anyone incase they want to visit me here... I hide away. I want to go to the doctor for medication but will that be enough? I don't think so considering how bad it is and not having the time to clean up. It's the school holidays for the next two weeks and I really want to be able to start cleaning up. I still have the kids here and the dishes and washing and it's worse when it's both of them here... usually number 1 is at school. They fight a lot. And hubby won't be here to help as normal. I know it's going to take months to get it back to an acceptable level... it feels like a huge mountain I can't climb... Do I need therapy? I also trace shapes eg the windows being square... tracing the four sides...

Yes, you need help. If the state your home is in is putting your kids' health in danger, you have to do something. Call someone (a professional) to clean the house for you and talk to a therapist and tell them this is too much for you. You don't have to rely on relatives, just ask a professional to help.
I doubt they'd take your kids away over this, but please don't put them in danger.
