My Roommate Got Admitted To A Mental Hospital And I Have To Pay For The Rent By Myself. What Do I Do?

Like the title says, my roommate (who I got an apartment with to help him) tried to hurt himself last week. The cops busted down the door and took him to the hospital, which he hasn't been discharged from since. He REFUSES to talk to anyone, even his parents, and I'm now in a horrible situation with a year long lease that ends next September. The rent is 1,400$ and I really can't pay for it by myself when you include utilities. It's not my credit on the lease, it's my father's. My landlord said that since his name is also on the lease, I have no ability to end the lease until I get him to sign some papers, which doesn't work because he won't talk to anyone. And it's even worse, because I doubt he's going to get out soon with his mentality. Tried to help the guy, got burned. Do you guys have any advice for this? Any resources that help with this situation? Please help.
