Energetically, you haven’t let go of them and at the same time you are still trying to find their energy. When you know someone, you actually know them as their energy signature. The more intimate you are with someone the more connected you are to that energy signature. You are used to getting up every day knowing that that energy (person) is there with you. When they cross over, you are still looking for their energy signature and when you can’t find it, you get confused. The emotional healing process involves acknowledging that their human body vibration has ceased to exist and that your body can now stop looking for their signature. It doesn’t mean forgetting them, it means acknowledging them in a different way.
