Oh boy! It sounds like your Mom is having some real problems. For one thing, she's desperately LONELY. She doesn't know what to do about it, so she comes to you.

Doesn't she have any friends?

Doesn't your father let her go out?

Do they EVER do anything together?

What kind of work does your father do?

Does he HAVE to work all the time?

Can you have a talk with him and tell him that you "suspect" that Mom is very lonely? You do NOT tell him what happened!! That is not your responsibility, and unless something else happens that's not appropriate, don't say anything. But he DOES need to know that she is VERY LONELY. He has GOT to start spending more time with her.

She also might need therapy. This loneliness may have gone into a severe depression which calls for therapy. There is NO SHAME in therapy, ok? That does NOT mean that someone is nuts. It just means that someone needs some help in dealing with some issues that COULD have started as far back as their childhood. That's what happened with ME. My childhood was awful, but things didn't really start showing until I became an adult. THEN I needed help in dealing with them, and I'm so glad I went into therapy. That MIGHT be what's going on with your Mom.
