Salam.

If we are sad , try and recite these:

a) la ilah ha illallah 1000 times each morning and evening without fail
b) istigh far 1000 times morning and evening
c) salawat Allahum ma soli ala sayyidi na Muhammad wa ala alihi sayyiidi na Muhammad morning and evening
d) Hasbiya llah wu lla illah ha illallah hi alai hi tawakall tu hu wa robbu arrshil azzimm morning and evening

God willing our sorrow will go away. Why? If Allah the creator of all creations including happiness and sorrow is in our heart , all the other things will go away. Try please.

Wa llahu alam
