How do I Do this!!!???

Last night my bf went to the ER room and later was told he needs to spend the night. I stayed with him all last night and only got about an hour of sleep. I was good this morning but now I feel absolutely horrible. We received bad news that he has to stay another night, so I'm planning on staying with him again. It's just that I am SO tired! I took about an hour nap today but that's definitely not enough for me. I am planning on buying Zzzquil & getting headphones that cover my ears (I'm such a light sleeper ear plugs don't work for me). AND on top of that, I have an interview at 11:30 am tomorrow morning. I don't want to be so tired that I feel sick & look horrible. I'm in college but I've never gotten this little sleep. How do people do it??? I need advice because I just want sleep tonight 😭
