am I U for being so pissed off at this attitude?!?

[Unreasonablebetty]

I struggle with personal relationships, I generally push people away because they act twattish at times, I fully accept Its a problem with me.
I'm very black and white in my thinking. And am VERY flawed myself so I'm not saying I'm perfect.
But currently I have a lot of mental health issues going on, I work part time from home, and I do a lot of market researches and am studying two years of my degree at home (I don't want my anxiety and general avoidance of people to derail everything whilst I'm working on myself)
So she thinks because I'm always at home I'm doing fuck all, when the truth is I am at home with my head stuck in paperwork either for husbands business, or doing my studying or generally doing one of the chores that's a part of being a mum or wife. So I get, what you up to today mate? I reply and say I'm doing something, ok no worries mate. So I think of for fucks sake. What does she want? If she wants something, just ask!! So I ask what do you need? Oh no worries, no worries mate. Or there's the joyful call me as soon as you can. And it's always something stupid that she needs, like she wants a net to clean her pool, and knows we have one for our hottub (never to be seen again!!) or a shoebox that she wants, or me to take her 3 year old over night, or me to buy her fags, or to babysit for her children, or help her clean her house. I shit you not. I've known this woman less than a year and she calls me for all manner of things.
I drop my daughter at a before morning school club (from when I was working out of the house- I got sacked and my daughter wanted to carry on going) and after school club (generally this is helpful with the work I currently do and daughter loves it) but I was getting these phone calls to take care of her youngest once I'd taken my daughter to school every day for about two weeks. And I would always get no worries mate.
It's all the time. I gathered she just wanted company, so I've done my best to be accomodating, I have her round for a few coffees a week cod she really seems to enjoy it. But she then wants to push for me coming round for dinner all the time. And every time I see her she's on about bloody utility warehouse and that I need to get all my friends signed up for her.
So we went to the cinema and it was all a kerfuffle about why her children needed car seats instead of the booster seats the cinema offered, and she needed to borrow money for cinema tickets and that was on top of the cigarette money she borrowed the day before. Then I mentioned it and she acted like I was conning her and ended up with£10 back.
So moving on, she wants my daughter to have dinner, this plan moves on to a pizza night.
The day of said night she calls me FIVE times to go over plans. Then she decides that she's gonna buy some bits, and calls like she's doing me a favour, like what can I pick up for dinner for you? Pick up some coke please I say.
That evening she's forgotten to get coke. So I say I'm going to pick up pizzas anyway. And she tells me she picked up her sons pizza without gluten so I don't have to,,, I think we'll to pick it up isn't a problem, we're going halves on pizza anyway aren't we?
So by this point she's moaning pizza isn't there when she's decided it needs to be. And does nothing but keep moaning that dinners late (6pm!!) she knew me and H were picking up pizzas. She knows what time he gets in.
Whilst we're there her 16yo son spoke to me like I was complete shit and she just stood there smiling.
I still haven't had the money for the pizzas (as a side note, the pizzas were for 9 people, 3 of which were in my family)
So I think ah I'll keep away from her for a few days,
Then she applied for a market research that is applied for (within a minute!) and has hounded me since. She's asked and asked when I've got it so she can book hers with mine. I told her tonight when I got a time etc, and she tells me she can't do it until the evening, so I say, as far as I'm aware they only have daytime slots, but check if they have slots in the evening I'll change mine and we can hop on a train together.

I get a message back saying ok mate, no worries.

I text back and say, no problem, I don't mind changing my plans for you x (I knew she was pissed off cod she doesn't want to pay for her own travel, she wants a lift from my husband- and it's not happening, not even for me!)

She texts back and says she's cooking her kids dinner.

I'm just having a bit of a moan but how can I stop this woman from seeming so utterly peeved with me when she comes with the expectation that I drop everything for her, and do so bloody much for her but if I can't meet this expectation she gets pissed off?
She seems to want all my time, she wants us to run around after her and her kids,
It's just tiring, I constantly feel like I'm being U but I'm trying to be her friend. Ahh, someone please tell me that I'm not just being a cow?! I'm really trying, this woman is quite lovely, but she just wants so much of me.

Just stop pestering her to reveal what she wants. After she says no worries, leave it at that. You are putting yourself in this constant cycle of serving her for no reason.
