Crystal recommendation for my mom to protect her from absorbing drama of everyone

[Bubbles]

My mother also has this thing of always wanting the best for other and helping and listening but this can go south sometimes.

There she is in her bed in her room minding her own business and then my aunt calls and starts talking about all nonsense **** complaining and they sometimes get angry at each other and my mother gets all this negative energy inside that sometimes cause to even bloat her belly (true, in TCM is said that people absorbing negative energies like sponge leads to bloating, it really comes from nervous system).

I don't want to give tourmalines or black obsidians to my mother, maybe some tourmaline around there might help sure, but I was thinking of a beautiful sphere on a stand for her to have, to protect and calm her and such.

No idea what to pick.. there would be many choices but this seems like a particular problem. If someone in family/relatives has some problem, she absorbs negative just by thinking how things could have been better if done xyz, or gets annoyed why others are 'that' stupid for example (she doesn't use this words but I am explaining).

Her fault is getting too much involved, but she also gets called on the phone by everyone and this is annoying (even at 9 AM/PM). Everyone when they are doing well and good when gone in holidays on the beach or other countries, nobody gives a call to share the joy. But when everyone have problems and drama, they all call my mother. Now I have to keep lots of things for myself and I don't want to cause further burden on her. A crystal won't fix it fully I am aware and I am talking to her about this subject to help her readjust herself.. but maybe someone her can suggest a crystal that would fit perfectly? She is Pisces in her late 60s. Thank you.
