It MIGHT be able to survive the gap if it's boosted to as high as it can be allowed before turning off the lights and locking the door IF SpaceX or Boeing can get their crewed Dragon up there and man-rated in time. If there's no-one on board they can switch off a lot of the complex life-support, ventilation and cooling systems. Bringing it back online after a gap like that is a daunting prospect though. I'm very sure a lot of people will be very nervous right now. It'll be a while before they have to make the decision to abandon it, but it'll be a hard blow either way.
Having to bring all the crew home WILL however no doubt mean an end to the research of a lot of scientists as experiments will have to be abandoned.
