Then don't have her to visit. You're allowed to make that decision. Agree with the others, stop accepting favours from her, she's using them as ammunition to attack you with.
Understand the game you're unwittingly playing with her. Nothing is offered altruistically, she has an agenda for everything she does and (since she does nothing "for free") a response she requires from you (as "payment") in return.
It's not about getting the parcel to you (which would be helpful because that's the result you want), it's about getting adoration from you by playing the victim and martyr. She'd have no doubt bigged up the hassle of collecting the parcel to something resembling world peace negotiations, then deliberately set off when it's raining so she could play victim about how you'd "made" her do that by asking her to fetch the parcel (which you didn't do anyway, but that doesn't fit her victim narrative).
Your role was to make her central to your day, fawn over her as guest of honour in your home for hours in return for this huge sacrifice she'd made in fetching your parcel. An act which would have been made out to be totally necessary because there's no other possible way you could have obtained this parcel if she hadn't and your Entire World would have definitely caved in if you didn't have it's contents (even though that's not true either). So basically she's saved the world, your life and is solely responsible for the continuation of the universe's existence and deserves to be treated accordingly. Instead, you just acted like a normal person and went to collect the parcel from her, thwarting her opportunity for drama and attention - how dare you?! 🤣
Regarding visits, she's treating you like staff! She doesn't have "days and times" for visiting, you're not running a day care centre for the lonely that she's paid a membership for!
Or setting things up so she can complain to others that you're treating her like staff, with her doing ironing and cleaning. Who goes into someone else's home and starts doing that without specifically being asked to help? 😵💫 She'll say it's helpful but it's not, it's overstepping.
I'd look into moving further away if you find yourself unable to set normal boundaries with her, which she will never stop pushing against and trying to reduce and eliminate, if she's a narcissist. I found trying to set boundaries with one is basically like fighting a constant battle because they never stop trying to destroy those boundaries. This situation is suffocating you and preventing you living your life.
People like to say on here that some people are too focused on boundaries but they don't understand that when dealing with self-centred and selfishly toxic people like this, if you're not forever totally focused on boundaries and assessing whether they're trying to overstep and whether you need to nip something in the bud, you'll turn your back for 5mins and find they've kicked those boundaries down completely and are now living rent free in your head 24/7 stealing all your peace. Or worse than that, you find they're now living rent free in your spare room, demanding to be waited in hand and foot and stealing all your time, energy and sanity, along with your peace.
No contact because of wanting a lift to work and to bring over a parcel sounds ridiculous when it's written like that, as if you're the crazy one. But it isn't, because it goes way deeper than a lift or a parcel. NC means you can stop fighting the endless emotionally draining battle of repeatedly shoring up your boundaries against their constant attacks. LC is worth a try, if for no other reason than reassuring yourself that you're not being unreasonable going NC because you've tried everything else and nothing works.
