Forget about it! Just get over it! How does one achieve equanimity? Certainly not by ignoring those issues in our lives that create anxiety, fear and imbalance. Such a philosophy is akin to pretending that the check engine light on our dashboard is not lit. Anxiety can be a valuable warning signal indicative of issues that need to be considered and perhaps confronted. If nothing else, awareness is often half the battle.
Talmud - Mas. Nedarim 22a
R. Samuel b. Nahmani said in the name of R. Jonathan: He who loses his temper is exposed to all the torments of Gehenna, for it is written, Therefore remove anger from thy heart, thus wilt thou put away evil from thy flesh. Now evil can only mean Gehenna, as it is written, The L-rd hath made all things for himself yea, even the wicked for the day of evil. Moreover, he is made to suffer from abdominal troubles, as it is written, But the L-rd shall give thee there a trembling heart, and failing of eyes, and sorrow of mind. Now what causes failing eyes and a sorrowful mind? Abdominal troubles.
What is remarkable to me as I read this is the physiological response that is being spoken of if we become worked up: stomach troubles.
The remedy for many of these troubles comes through conditioning. One must approach whatever is disturbing and confront it. Understand it through touching, feeling, questioning of intention. Seek the root of your discomfort. Many times our reactions to situations obscure the real root of the problem. It is much easier to condition one's self once the root is addressed.
For example, if you are overworked and any new tasks make your existing work unmanagable, perhaps you should try organizing your workload by making lists and prioritizing the more important things to do. By writing them down, you don't have to remember all the details. As new items arrive, simply adding them to your list can help eliminate some worrisome thoughts.
