Can’t be with him for surgery

So we already knew my boyfriend needed surgery but he just got the date today. It’s only 3 weeks away and I have to be in class. It’s the last week of CNA classes and I can not miss it or I’m out. I’m really stressed about his surgery. It’s open heart surgery so pretty major. I just really want to be there with him. I almost feel guilty like it my duty. I won’t even get to see him until he’s home most likely with the local hospital visitor rules.

He already told his mom that she needs to keep me updated. And he said he would actually FaceTime (he hates FaceTime).

Any tips? I know that after it’s all done. It’ll be good since he will be better and I’ll be done class. But I really want to be there
