False Hope
I've done my best. and, my colleagues believed me can solve that.
Because I took too much time to spend in the company for that, my wife also sacrificed for a month.
I devoted all my time to solving the problem, and still failed. I'd have had to do not give false hope.
I've done my best, but, it was not the best.
It was the torture.
