If you are really mad you can punch your pillow. Maybe you can talk to a parent about these feelings. Or, if that doesn't feel right, find someone else you really like to talk to, maybe a teacher or neighbor or grandparent, and talk about how you feel. It's tough to let it out, but it can really help. If you have a friend whose parents are divorcing, maybe you can try to be a good listener when your friend wants to talk.
Some kids feel better after talking to a psychologist or social worker.
These are adults who are trained to talk with people about their problems. There are also lots of good books about divorce that were written for kids. When parents divorce, their kids generally live with one parent and visit the other. And you can feel good knowing you have two homes where someone loves you. There are common problems, though, that sometimes come up when kids visit one parent and then go home to the other.
