Clingy, needy, pestering 7 year old

[Anditgoesoff]

I also have a 2 year old.
I'm currently sat on my bathroom floor upstairs crying.
She can't leave me alone. She talks incessantly. She follows me to the toilet.
I've organised a little party for her and her brother for New Year, they have their favourite songs on, balloons, sandwiches, fruit fondoo, chocolates. I've danced with them for 45 minutes before eating myself. But she wants this song on, that song on.. She then asks me for more chocolate, I tell her she is allowed 3 more and she is to spread them out throughout the rest of the evening.
I think she'll stop asking.
She quaffs 3.
Then asks me for crisps.
No more food other than fruit.
She asks for breadsticks.
No more food other than fruit.
ONE more chocolate.
I snap at her.
She says sorry.
Then follows me to the toilet trying to open the door.
She wants me to dance.
I go and dance.
She tell-tales on her brother for eating chocolate (he hasn't had as much as her).
I tell her to stop the pestering.
She tell-tales on him again.
I go upstairs.
5 minutes later the door handle is going... "mum, mum, mum, mum you ok in there"
I've barely heard a peep out of the 2 year old in 1.5 hours.
I've told her off for pestering again and sent her downstairs. Sat here crying because she never ever leaves me alone.
Meal times are the Same.
How many bites until pudding?
Can I just have 2 more bites?
Why no pudding?
We had pudding last night?

I'm really starting to dislike her and I feel awful for it. I just want to get away from her.

Help?

Its hard isnt it during lockdowns and your not getting as much help perhaps as you normally would. From what you described your daughter is lovely and just a normal active 2 year old, but it can be tough as a parent especially during these times, have you tried finding something she really likes doing during the day, that can keep her occupied for longer? X

What other social outlets does she have? This sounds like it will be impossible for her not to pick up on the "mum is annoyed with me" vibe, which will fuel the behaviour, and really not strengthen her self esteem.

My sister and I couldn't be any more different, extrovert wise. I'm an introvert, she's an extrovert that (inexplicably, to me) needs lots of social interaction. I'm your 2 year old, could play for hours alone, while my sister was exactly like your older one, very needy and now has a large circle of friends and loves a busy home. Is this the cause? I.e. part of her personality. Or is she feeling unloved, has there been changes to family or home or school etc? What support does she have from school?

You sound like you don't like her at all, please figure out how you can make this better for both of you, because I know I'd feel the same as you, but it sounds awful for both of you

She's very extrovert.
And a huge sensory seeker.
I'm the opposite.
She struggles to keep focused and can't watch a film without incessant talking etc or focus for very long. I'm a little concerned as although I know DCs can be a little full on- she seems more full on than most.
I spoke to the doctor once as I felt like I was drowning in her demands. He suggested me taking her out 1:1 twice a month- then I found the behaviour actually accelerated when we came home as she couldn't grasp why my attention wasn't still focused on her.
My Mum has commented that she seems "too hyper" several times.
