But really, you might benefit from talking with an attorney. Again, this is not a legal opinion of anything on this site.

You may be able to find a suitable sub-tenant to replace you, but again you will need to refer to the lease to see if that is possible, under what circumstances, and at what cost.
They may be willing to work with you if you agree to do the marketing to find the new tenant. Obviously, they will run the application, etc like they did on you. But, if you are willing to take the stress of sign calls, showings, etc off their hands, who knows.
Luckily, homes in Grapevine lease rather quickly, so securing a new tenant shouldn't take too long.
Best of luck!
