Parental Alienation occurs when children resist or refuse to have contact with a parent. For the receiving parent, this is an unbelievably terrifying and painful experience. The parent never knows for sure if they did something wrong, if the child is being influenced by someone else, or if the child is just passing through a phase.
Parents experiencing alienation go through a wide range of emotions. They can experience denial about what's going on by telling themselves it's just a phase. They will experience fear that it may never end and because their child is unreachable they feel powerless. Inevitably this leads to anger and a desire to blame others. Ultimately parents experiencing alienation go through sadness and may even grieve the loss of the child if the alienation goes on for a long period of time.
