My mom - need advice

I’ve been feeling so bad for my mom.

She takes a lot of abuse from my dad. Both verbal and emotional.

It’s soooo sad to see my dad act like that behind closed doors and then turn around and be the happy- jolly person that our neighbors and family loves. It’s a really weird thing.

We don’t talk about it in our family and after my dad has an outburst she acts like nothing happened and everything’s fine.

She’ll say things like he’s so good to me, he’s such an awesome guy. And I’m like really? Are we talking about the same guy?

Anyway, I feel like my mom is going through some type of depression. She haaaates her job and is always late for it. She says her boss doesn’t care. All she does is takes care of my grandmom, her friend who has cancer and her aunt who has cancer. That’s all she does on the weekend.

She never does anything for herself. I try to talk to her nicely about going to the gym but she doesn’t go and just keeps eating. It’s so sad and I don’t think she realizes it and thinks this is all normal.

I don’t really talk to her about this and I don’t really know what to do.
