Hello!
Do you have the possibility to help people in your job? I mean, make their lives happier. Helping to solve their problems.

Many times, helping others is also helpfull for ourselves.
Perhaps, this could be a starting point.

Eh...it's also very important to dedícate something you like or you were born for. Everyone has a special ability to do something. Is it possible to change job in a short-term?

I'm sorry you have to deal with this feeling of emptiness.
