IMHO, you should definitely reflect on why you feel that "leaving is not an option". Is it because of the money? Pay off your loans, downgrade the location/size of your apartment/house and suddenly making only half the money will no longer be a problem. Is it because of all the "opportunities"? (Are you absolutely sure that does not mean "opportunities to have no personal life and to potentially lose your mental health"?) Realize that many brilliant techs consider "a dream job" to be "a job they love" as opposed to "a job for a famous company". Finally, perhaps also realize that being that tired, you might not be able to ever maintain a romantic relationship, not to mention starting a family. It might or might not matter to you down the line - you have to figure it out.
