7 months pregnant and my 3.5 yr old is driving me crazy!!!?

I can't take it anymore!! My husband is no help..he just wakes up so he can leave, my car is broken so I've really been stuck at home with my toddler..she's having some sever seperation problems. She's started waking up 4 or 5 times a night and screaming untill she gets to come in our bed. She's just like glue to me..but whe I want to get her dressed or brush her hair..its a long drawn out ordeal..with screaming and hitting..she's 50 lbs and when she starts flailing I just start crying..I can't take this anymore..I've been having a hard time with this pregnancy..been nauseous the whole time...when she isn't driving me crazy my husband is stressing me out...I know he's stressed about another babyamd the fact he's "gettin old"...but he just dosent care to help me one bit..he dosent help cook or clean. He works one day a week and dosent ever ever take his daughter with him anywhere..I'm going crazy!!
