Feeling bad or happy?
Feeling sad isn't always a bad feeling
for feeling happy isn't always a good feeling.
If you're happy, but your happiness is based on something from the world i.e. your job, your wealth, then the feeling is temporary and it can turn you upside down when Allah Swt decided to test you on it.
However, if you feels happiness because you have made Allah Swt happy, insyaAllah, however he tested you, the feeling is for eternity.
