Disorientation
It is not unusual to feel confused at times about what day it is or what you should be concentrating on. You may find yourself asking, "Why did I stop at this shop?" or "What was I just saying?" These are common reactions as you try to deal with an overload of stress. It may also be that your mind is so preoccupied with the death of your baby that the day to day routines lose their significance making it difficult to concentrate.
Parents often feel confused and frustrated possibly expressing feelings like "What am I meant to do now? I was meant to come home with my baby, I should be busy being a mother, a parent". These feelings are normal as you try to make some sense of your life without your baby. In time you will adjust and regain some direction.
It is not uncommon to suggest changing jobs or moving house in an effort to 'make things different'. Take time to consider any major changes. Sudden change at this time can also be a major stress and will not lessen your grief. It could also contribute to you feeling more at a loss.
Sometimes one or both parents will look for ways to busy themselves. This is an individual way of dealing with the grief and possibly a way of trying to avoid the depth of pain within.
As a bereaved father, it is not unusual to throw yourself into your work or hobbies or feel you have to 'provide'. Work colleagues can avoid you or try to help you in ways that are not helpful. It can be difficult to express your true feelings or have opportunities to share them with friends or family. Our society is not as open to men expressing their grief, but hopefully this is changing.
Perhaps you will feel that you have to be 'strong' and support your partner. This may be true but acknowledging your own loss is also important and your partner may interpret your composure as not being emotionally affected by the death of your child.
