What the heck ?

Hey all so I currently live with my grandparents me and my boyfriend just moved in in October. So my grandpa was talking to me today and pretty much said I'm more than welcome to stay but I need to hurry up and get done with school so me and my boyfriend can move out. I'm a nursing major and am almost done with all my pre reqs I currently work at marie calendars but I want to quite because I am working 5 days a week and can't focus on school enough and if you know anything about the nursing program it's hard and stressful. I had an A in the class until I started working and now I have a D ? but with my grandpa making comments like this it's making me freak out and think I should keep working I'm so confused. I can't work 5x a week and take nursing courses it's impossible!!! Any advice would be helpful.
