Hello everybody

These days I was am very busy. I have had a lot of work last week and I had three days free (better - three free days) . I love to be in my house with my family. I returned to  at my work. Searching for answers, I felt grieving !!! *

Have a nice night !

* "I felt grieving" isn't quite right.  Grief is more what you feel when someone dies.  You could say "I felt bad" or "I was unhappy"   or  "I was sad".  Not sure any of these are exactly what you are trying to say but they come close.  Maybe something like "It was difficult for me as I searched for answers".
