Be happy!

Hi,

"Eulogies and fasts are prohibited on the seven days of Pesach and the eight days of Succot, along with other holidays. One is obligated to be joyous and of good heart on these days - him, his children, his wife and the members of his household, and all who are joined on to him, as it is written, ‘You shall rejoice on your holiday, etc.’

"Although this joy refers to the Korban Shelamim, as we explained in the Laws of Chagigah, it also includes the joy of a person and his children and household, each with whatever is appropriate for him."

(Rambam, Mishneh Torah Hilchot Yom Tov 6:17)

Chag sameach,
Mordechai
