Just keep yourself busy. Work, work, work!!!
focus on solutions
Always point your mind to "way out", so the problem can be solved as precisely and immediately as possible. If you feel the problem can be controlled, then the next step is you should be able to prevent it from happening again.
Dare to take some options, just in case the first solution does not go as planned. You still have second and third planning.
Focus on things you can control, such as your attitude and effort.
