What do you think of me not crying when my dad died?
Why did you fake your tears for your dad?
Because I had planned on taking out all my anger on him.
Losing a parent can be an emotional experience and you may not understand why you feel the way you do. It is normal to feel a range of emotions, including anger, and to not be able to cry. A therapist is a good idea for helping you sort out your feelings.
I have no idea how to behave when someone dies and I hate feeling bad. Crying sounds easier in the long run.
Usually a child cries when a parent dies. If you are confused by your feelings you should talk to someone.
