My mom is weird help!..........?

You're mom could be having anxiety attacks, and wondering how her life got so off of what she planned. Most parents do not plan to be divorced with kids. And maybe she just needs a lot of help right now with life and your grandparents are there for her. She might also have autism, which is a mental disorder that causes people to not grow up, they don't like too much change, and they just don't understand social etiquette. It's just a suggestion though.
