<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've been married for 1 1/2 yeas. I'm 29, my husband is 32. Apparently, one of my husband's cousins is having a baby shower this weekend in another city and my mother-in-law wants me to ride with her. I never got an invitation, but I inadvertently saw an email the cousin sent to my MIL asking for my address to send an invitation for the baby shower. I'm thinking she may have not given my address to her and instead told her that she would tell me about it. Not sure why she would do this, but that's what it seems may have happened.

The problem: the thought of being trapped in a car with her for four hours (two hours there, two hours back) by myself makes me want to shoot myself. She likes to pick at everyone all the time and will ask questions just so she can  ask you why you are doing what you are doing, tell you that you are wrong, and then tell you what you should do instead. I imagine the trip will be filled with four hours of belittling me, acting like everything I do is stupid and getting all up in my business.

She actually is a good person and does lots of awesome things, but I always have to make sure there is someone else around as a distraction so she doesn't get fixated on interrogating me. She does this to everyone in her immediate family, not just me. I got the distraction idea from my sister-in-law. There isn't anyone else who can ride with us. My husband has to be in town that day and all the other female relatives are coming from other cities. My husband told me he wishes I would go, but he understands why I don't want to and promised to get me out of it. I feel bad about not going and would like to be able to go to the shower, but thinking about being stuck with my MIL for that long is giving me an anxiety attack. Should I just take a Xanax and suck it up?
<bot>: I'm terrified of being stuck alone with my nagging mother-in-law, but don't want the rest of the family to think I don't like them.
