For my Dad how is a dialysis patient

Hi I am 19 years old and a student. My dad work in post office his kidney failure before 4 years now is going for dialysis 3times a week. He is very hard working person. Being a patient he goes to work. And runs the house. 😔. I also go to work because the money my dad earn is not sufficient. So after my college I work as sales man. But what I earn can one help in paying bills and my college fee. My mom and dad didn't go anywhere out to travel. .And may be becuse of that I think they really depend. Because they think if they will go out some were money will be shot. So I have saved some money but it's not enough for them.so that I can give the little bit of happiness. For what they have done for me and my family. I want to give my dad happness so I'm trying to get some money. 😇
