I am so angry, what should I do?

No matter what happened during your marriage, keeping your head straight now will result in a much better future for you and your family.  Going through a divorce is rarely an enjoyable experience, but you would be surprised how many people just like you have survived the experience. Consider going to therapy or meeting with your minister, hitting the gym more often, or taking up a new hobby.

It may be difficult, but actions based on emotion could significantly hinder you during a divorce, especially if you have children.  For example, one of the many factors the court looks at in determining parenting time for your children is your ability to encourage a relationship between your children and your spouse.  If you trash-talk your spouse or make it impossible for your spouse to see the children, not only are you doing a disservice to your children, you also are hurting your case since you will likely be facing evidence of your actions before the judge.  You absolutely will benefit in the long run from being the bigger person.
