I think it is fascinating that people's minds are so powerful that the way they think about situations will determine how they feel. In the 1831 there was a cholera epidemic and Rav Akiva Eiger was asked about taking measures to protect one's self from contracting the disease. HIs recommendations were prescinet. Among other directions, he advised social distancing. In his letter to his student he also impressed upon him the importance of not worrying and not getting depressed.
The video attached below is in Yiddish with English subtitles. Rav Elimelech Biderman is the Maggid of Jerusalem. He speaks multiple times every week in both Hebrew and Yiddish, and his words have been translated into many languages. He is arguably the most popular teacher of Torah today. In this short clip he also speaks about maintaining a positive and happy attitude.
I wish you a relaxing and happy Shabbat Shalom and Chodesh Tov.
