You might be able to think more clearly what to do with the cause of your anxiety then, and you might be able to solve it in the short term resolutely, and then move after resting to long term solutions with relaxed strength.
Telling someone also works. If you do both at the same time, the natural control you might be aware of should allow you to resolve the problem to your best long term feelings.
