Torn between 2 devils

Source

Have you ever come across a difficult decisions whereby either way you decide, you end up hurting?

Staying on/not deciding is also just as painful as letting go/leaving. The only different is one is a constant repeating daily torture for as long as you hold on, while the other is a deep pain for weeks or months maybe until its finally gotten over.

People may not really appreciate you for staying on, but leaving may make them hate you.

So how would you made up your mind on which decision to made if both are equally painful tough decision to make? How do you know which is the right decision?
