I'm really sorry about what you're going through. I will suggest you just continue and try to make things as best for you as possible. You can always hope things will be better in another life but unfortunately no one is quite sure what happens when we die. The key will be to make the best of what you have here. I'm still learning to accept this myself, as a young person learning that when things are rough you need to do what you have to do to make the best of it and stay strong. Now my situation is not the same as yours so I don't know exactly what to tell you, except what I said before.
Keep your head up. I hope things get better for you.
