Need help writing an INFJ character.

As the title says, I am in the character development phase of my story and I would love to gather some insight from you guys. I've already indentified him as 9w1 enneagram, if you are a 9w1 INFJ please comment.

Some things I would like to know:

• How you usually manage stress in your life?
• How do you cope with the loss of a loved one?
• How do you feel (and act) about major changes in your life (career change, life purpose change, etc)?
• What kind of behavior is personally offensive to you?
• What's your behavior towards someone you don't trust?
• Can you describe your anger outbursts?
