help a son help his father

My father recently got confined in the hospital again. (pic is an old pic of him also confined) But this time, he got really weak and doctors diagnosed it with meningitis and a thyroid storm. My father survived through four cardiac arrests and is now in stable condition but still recovering. And the hospital bill is not getting any smaller. This is my first time in using this platform, and this is help my family in any way i can as his son. He is a single dad, with four children. though he has his girlfriend to help our family, my father is the main breadwinner of our family. Im not expecting much but any amount will be very much of help to us
