The mind does not tell the difference between suffer and pain.
The truth is that pain and suffer are two different things. Pain (emotional or physical) is a feeling, a feeling of a thing undesirable that is there in the body or in the psyche, a thing that inflicts a feeling of pain (a painful emotion, an injury etc.) while suffering is our response out of identification with the pain. Watch it and you will see the difference by yourself.

The mind believes that suffering is caused by the pain and thus tries to resist the pain.
The truth is that suffering is caused by the very resistance to the pain, not by the pain itself!

This opposition in views between the mind and the truth is the greatest misconception, a misconception that leads to the tragedy of human beings.

The mind in its very attempt to avoid suffering causes the suffering. What greater tragedy can you find? The supposed antidote happens actually to be the poison itself.

Instead of resisting a certain pain you have, try for once to accept it, give it a try, what can you lose? Acceptance means to let the pain be there, not trying to articulate a way to chase it away, not trying to reason it away.

When you reach a true and total acceptance, you find yourself suddenly disconnected mentally from the pain. The pain is still there and is still sensed but you are not affected by it anymore, you do not suffer from it anymore. You don't mind whether it is there or not. The pain is still there but you do not suffer, you find yourself living side by side with the pain and being able to smile at it as if it is a pain of somebody else. This is the mental state which is sometimes called the IDGF state. It is hard to describe this strange mental state in words, it may sound contradicting and so unexpected to the mind. Try it and you will see the truth in it by your own experience.
