Help needed

Hey...I don't even know how to start asking for help again. Unfortunately, for those who already know, but also for those who don't... my mother has serious health problems. In October we discovered that she has a brain tumor, to which were added cerebral atrophy and a cerebral stroke, after which her medical condition got from bad to worse. Currently, she is immobilized in bed, but she is stable following the stroke. The biggest problem remains the brain tumor. There are moments and moments. When she is better, when she doesn't recognize us, when she feels better, when it doesn't. She needs medication that is extremely expensive, and for which, with great, great regret, I must admit that we cannot afford it. Any help, any gesture is greatly appreciated. Please believe me, if I could have done it differently, I would have already done it. I call on your help again and I will be eternally grateful to you. Thank you!
