I hate my mother

Feeling the same way about my mother. Everything she says, does and like someone else on here said even the way she walks is annoying.And she loves to play the "victim"... She claims she does so much for me it's a fucking joke. She's unemployed with nothing to do all day. I'm 8 months pregnant and have a 4 yr old. So if i ask her to come over and help she has "things to do"...like what are you doing watching a lifetime movie!?...She is constantly complaining about everything. Being tired (she sleeps in till 11am everyday)...Her back hurts...I can't stand listening to it! I'm 8 months pregnant work as a hairdresser on my feet all day and I have to listen to her complain. Then when she does come over to help she's looking for an excuse to get the hell out. Like why bother and everytime I'm around her where always fighting. I have alot of resentmet towards her she never played with me as a child and I see her do the same with my son. She's just lazy. She's very cheap also, even to what I spend my money on. She thinks I shouldn't throw my son a birthday party because it's too pricey....Like are you kidding me!?... It just brings me back to my childhood all over. We weren't poor just no one gave a shit I would wear the same four shirts to school because She was either to lazy or too cheap to buy me new ones. Not to mention my raging acholic father bascially raised me because she just couldn't be bothered because she was just "too tired" when she got home from one of her dead end jobs. My father is a whole nother issue, but really dealing with her can you blame the guy for drinking!?...Sorry so long have to vent....Is this normal?
