<human>: So tonight, I noticed my mom crying on the couch, red faced and extremely sad. I sat next to her and began asking why she's sad. My mom explained to me how she feels extremely unappreciated around the house and how she's starting to feel unwanted, and has no one to talk to. She gave me a few examples of what my dad and I have done lately and I really did feel bad, so I apologized. My mom and I are fairly close so she was accepting, but she finally broke and told me how she feels like my dad is just downright negative towards anything she does. I have noticed for quite some time how my father has become more aloof towards my mom and how his jokes become more and more insulting towards my mom (IE: Calling her greedy when she offered him some cake but gave him a slightly smaller piece) and she can't really handle it anymore.

 Normally people would have someone to talk to, but we are a small family of 3 and have no relatives at all that live on the same continent as us. So we have to fend for each other and it seems to be taking a toll on my mom. She asked my dad if he wants to exercise, go to counselling, church, etc and he responds with how he's too busy with work to bother (we recently moved houses, he's paying for half my grad car and supporting family back home) and he doesn't have time to waste. My mom thinks he's being overworked since he's always doing overtime to the point that she thinks he thinks work is more important than anything else at this point. I offered to my mom that I could talk to my dad about how he's making mom feel horrible and unappreciated (even when she does a lot for us, with a huge smile to boot) and try to talk it out with him. She said that was a bad idea since he would get mad that she vented to me about him and she wants to avoid it. I'm not really sure what to do, I feel like my dad would get mad if I confront him, and if I let them go about it, my mom will start to sink into depression at this rate. What can I do?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Mom feels like shit because my dad is extremely unappreciative and insulting to her these days but she doesn't know what to do or who to talk to. Help?
