i'm really sorry your mom is being so unreasonable. maybe you can tell her what you said about this being a time when you could really use her support rather than her making special requests of you that will put added stress on you. while i would be tempted to let her rent a car and just drive herself down i know saying that might start a huge drama at an already stressful time if your mom isn't used to you setting strong boundaries with her.

i recently set some really firm boundaries with my own mom who also just assumes i'll do what she wants, instead of asking, and i know she was really unhappy about it. i figured though that i'm way past the age of having to kowtow to her expectations. when i considered my age (40s) and that i was really letting her get away with still being so controlling i realized how ridiculous it was that as a grown woman i still don't allow myself to stand up to my mom. i seemed to have hit some sort of limit with her shenanigans and now feel like i'm just going to be true to myself whether she likes it or not.
