About your problem of anxiety and ask my advice.

Freely adapted and translated
26 Teves, 5725 (1965)

This is to acknowledge receipt of your letter with the enclosure, in which you write about your problem of acute anxiety and ask my advice.
The best and most effective thing to do in a situation such as yours is to study thoroughly those sections and chapters in our sacred books, such as Chovas HaLevavos, Shaar HaBitachon and the like, where the topics of hashgacha pratis (individual Divine providence) and bitachon (trust in G-d) are discussed.
It is well to keep in mind those chapters and verses in Tehillim (Psalms) that speak of these subjects, as well as the Midrashim and commentaries of our Sages on them.
These topics should be studied in such depth that they become part of one's thinking. In this way there will be no room left for any kind of anxiety or worry and, in the words of King David in Tehillim: "G-d is with me, I shall not fear. What can man do to me?!"
As you well know, belief in hashgacha pratis is the basis of true monotheism, a concept which for us implies not only that G-d is One, but that there is oneness in the whole of Nature.
In other words, the whole universe has one Supreme Being, Who not only is the Creator of everything, but is also the Master, continually supervising every detail of His handiwork.
The corollary of this is that there cannot be a single thing in the whole world that is separated from the Supreme Being, or in any way not subject to His control. At the same time, it is obvious that the Supreme Being is also the Essence of Perfection and Goodness.
And although many things in the world seem imperfect, requiring completion or perfection, there can be no doubt that there is a perfect order in the world: even that which is lowest in the scale of Creation, namely inanimate objects, display wonderful perfection and symmetry, as can be observed in the atoms and molecules of inorganic matter.
Hence the conclusion must be that even those things that require completion are also part of this perfect order and necessary for the fulfillment of the good, all of which is explained at length in the teachings of Chassidus.
It is further explained that in order for man to attain perfection, it is also necessary that he should have the feeling that he is not only a reci-pient and beneficiary of the Divine order, but that he also plays an active role in contributing to it.
Indeed, according to the expression of our Sages, of blessed memory, man has the ability and option of becoming "a partner in creation." This is why many things have been left in the world for man to improve and perfect.
I also want to make a further observation - and this is also essential for your peace of mind - that there really is no basis for anxiety at any time, and as you yourself mentioned in your letters, that you find no reason for it.
Even in such cases where you think you know the reason for your anxiety, the reason is undoubtedly imaginary, or at any rate, not the real cause. For the real cause is that one's daily life is not in complete harmony with the true essence of a Jew.
In such a case, it is impossible not to have an awkward feeling that somehow things do not seem to fit, and it is this disharmony that is at the bottom of the anxiety. Moreover, this anxiety is in direct proportion to the discrepancy between a person's lifestyle and his true and natural self.
We all recognize that anxiety has to do with the psyche. But in the case of a Jew, the so-called psyche is really the neshamah, the soul. Some Jews have particularly sensitive souls, in which case the above-mentioned disharmony and discord creates an even greater degree of anxiety, and even subtle and "minor" infractions suffice to bring it on.
But even in the case of an ordinary soul belonging to the average Jew, some anxiety must inevitably be created if there is a failure to observe the fundamental mitzvos (commandments). It is very possible that the above may have a bearing on your situation.
If this is so, then all that is necessary is to rectify this matter, bringing your daily life and conduct into complete harmony with the essence of your soul through strict adherence to the Torah and mitzvos. Your symptoms will then disappear by themselves.
It is also necessary to mention that in your case, where your position gives you a great deal of influence over those around you, your influence must be an integral part of your harmonious life, and it is therefore essential that your influence too should be in harmony with the Torah in the fullest measure.
I would also suggest that you have the mezuzos of your home checked, as well as your tefillin, and that before putting on your tefillin every weekday morning, you put aside a small coin for tzedakah (chairty).
