That depends on how you feel about it. If you enjoy what you have achieved and take it with you, but also accept that when the CB is closed it can no longer exist, it might be easier for you.
The important point is not to chase after what is impossible to get. And if you accept that and let it go, it becomes easier.
This is generally true. Don't spend energy and time on something you can't change. Only do it where you can.
