Bridal Shower

My bridal shower invitations went out yesterday and people started receiving them. My aunt called me freaking out because "OMG how is grandma going to get there if my Mom doesn't go?!!!" because heaven forbid someone else has to pick her up

Honestly, I don't know if I can trust my mom in such a small space with important people. For all I know, she will arrive and she will sulk and be annoying the whole time or start to make a scene. My aunt said she would be responsiible for her... but I'm still kind of nervous.

Do I invite her? or not invite her? Honestly I'm still on the fence about inviting her to the wedding too.
