Mother is very leading a very lonely life, suggestions please.

So for context, my mom( in her 50s) spends her entire life inside the house all day everyday. Sadly she is a victim of patriarchy and spent her entire life taking care of my dad,my grandfather and her two kids. Now me and my brother are grown up are abroad leading our lives, grandfather passed away. Dad is busy with his work and wants mom to stay home, typical indian family bs. She has nothing to do, but has been practicing yoga intensely for many years and is very good at it more than she gives herself credit for. If she goes on like this, she will lose herself and i dont want that to happen, she’s already showing signs of depression, runs in our family.. Any kind of suggestion would be of great help, are there any groups she could join? Anything people are aware of that could get her out of the house? Thanks, sorry for the long post but i would really appreciate some input or help here. Much love, Thanks!
