I wonder if she actually has some medical issues, where she has to go on and on until she runs out of steam. No wonder she hasn't got any pals, how anyone could put up with her constant ramblings and when she does her yakking on her stories she just absolutely loves the sound of her voice
My Auntie does this - it's not fully medical she's just an
hole. She gets very obsessive and will go on and on and on and on about things. She can either go full on or down the "subtle" digs and passive aggressive route.
Example:
Cousin A's wife asked Cousin B, who loves to bake, to make a birthday cake for her Son's first birthday.
My Auntie rang Cousin B and was moaning about how she should be providing the cake as it's her grandchild and Cousin B shouldn't be doing it. The week leading up to this birthday she was getting increasingly erratic about this cake. She was told quite firmly by my Nan, Cousin A and Cousin B that she wasn't providing the cake and if she couldn't behave not to attend the tea party for the baby because life isn't all about her.
She has also been frankly awful since the decision was made to remove my Grandad's breathing tube and let him pass with dignity. She keeps making comments to my Nan about if Nan had been able to perform CPR he might still be alive and she (Auntie) shouldn't have let them remove the life support as he could have made a fully recovery (100% he couldn't) etc. Nan tried to be understanding that people process grief differently but eventually lost her
tit at her and has refused to speak to her at all about it.
As you can see, like Lauryn, she goes off on anything and everything with absolutely no filter or thought. The difference is my Auntie has people who tell her when she's going too far, she is held accountable for her actions and is expected to moderate her behaviour acaccordingly.
Lauryn must be similarly draining for her family - I can imagine her moods and tempers - they've obviously chosen to pacify and appease her rather than challenge her behaviour and insist she seeks a professional regarding the more extreme aspects of her behaviour. Unfortunately, they will snap eventually and Lauryn will have to adjust very quickly or she'll be completely alone.
I think Amelia will be the first to really lose it with her, just a hunch.
