How to Deal With Pain?

The best way is to understand it. Ultimately it will boil down to pleasure and pain survival circuits. Then start living in the moment. Suffering is optional. Everything in life is overrated.

Pain served an evolutionary purpose during earlier times. It still does. But a lot of things have changed due to human progress. However,  to some extent, biological circuits tuned over a million years are still operating in previous mode.  If you think about it, there is no reason you cannot override the pain.

Stop playing the victim. Instead plan revenge. This will also help in overcoming pain.
