Ican completely relate to this because my Mother is practically the same way. She attracts work drama all the time and i tell her she just needs to let it go but instead it is all she talks about lol. The worst curse of being a healer is you can’t help your loved ones if they aren’t willing to help themselves first. The best thing we can do for them is give them love, show them we care, express gratitude to them and imagine light filling them with the loving energy they need to move out of their depression.
Its like the saying you can lead a horse to water but you can’t force him to drink. We can try to teach them things to help them change but until they change themselves, our teachings are useless to them. I think it comes from a place of Acceptance, this is her path right now, we don’t always understand the place they are coming from but everything happens for a reason. Maybe she is attracting these circumstances into her life because she needs healing, maybe these circumstances of negative behavior are showing her own cycles and how she needs to break them and release them. We can offer advice, help guide them or show them the door but they always have to be the one that walks through it. I can give you the canvas but you have to paint the picture.
So i think the best thing you can do for your Mom is tell her you love her, show her you care, listen when she talks by looking into her eyes and showing her you understand. Acceptance of respecting her path but also giving her healing light to help her. Even something as simple as talking to your angels or your guides might help. Ask the universe for help for your mom. The Universe has this beautiful way of granting prayer, Ask and you shall receive.
Help show her, her own light that she needs to see through the darkness. <3
I send love to you and your mother <3
