Thank you for your Question
Very sorry to hear about your mother. InshaAllah that her health is restored and she feels better
For Evil eye pls recite Surah al-Qalam: 51 and 52
Recite the above 7 times and blow the breath towards her.
Also, giving charity is highly recommended.
On a side note, you should get your mothers medical check done including blood evaluation. Sometimes a small underlining cause can create a drastic reaction. Depression and anxiety can also be cause by sever lack of vitamin D3.
InshaAllah that she feels better
