Sadness can range from terrible crying fits to just a general feeling.
You may feel this way for some time during the divorce and for a period time after it has ended. You may also be surprised that this feeling my return from time to time months down the road. This too is normal. Anger - It is normal to feel angry. You may feel anger toward your spouse, yourself, the situation in general, or even God.
