How can you?

A passionate person can no more turn to 'ice' than a stoic person become passionate. Whether it's genetics / environment, we are mostly what we are. I know that - for myself, when I'm hurt or pained, I have to have quiet time to sort it out... prioritize in my mind and focus on the things in my life which are most positive and constant.

peace and best wishes.

You must learn a new method of turning a neg into a postive become an actor outside your body and belong to someone other than yourself and learn something new the main thing is to become involved and not have so ,much time to think of just your feelings a lot of people out there are just trying to find a meal to eat so why not cook something and take it to the homeless shelters or help out there,,,

There are always cold/dark sides to life.

Without them you would have nothing to make a comparison with the good and wonderful aspects of life.

You can't. The pain will still be there and it will manifest itself as anger or self-destructive behavior, or depression. Live through the lows and the highs will seem much higher.

by not allowing things to affect the way you act by not reacting to things and situations that may arise against you...
