Why do I just want to die? Is there something wrong with me for feeling like this?

I understand where you come from. From my personal experience, many people go through such a phase in their lives. It feels like everything has come crashing down and that there's no point in trying anymore. Giving up feels like the only thing left to do. In such situations, all I ask you to do is just think about how far you've come. I mean, you've gone through so much and still bore all of it, so just imagine how amazing you'd turn out if you got through this one thing. The fact that you've come this far just shows how strong you are. Trust me, if you make through this right now, you'll look back to this phase in the future and thank yourself for not giving up. Strive harder to make things better and I guarantee you, the universe will listen to you some day or the other and everything will be better.
