I'm confused

Every time my Friends are going through a rough time I ALWAYS make sure that I can do everything and anything to help.But with me it's another story, like a week ago my dad went to the hospital and I was stressed af because I take AP classes.So I basically had to do my homework and "sleep" at the hospital.I mean they would ask how I was doing but they wouldn't help me, like at all.And don't get me wrong I'm thankful that they ask.But I feel stressed and worried all the time.I don't wanna lose them.
