The atmosphere should be gentle-kindness. Bathed in love, understanding and forgiveness. Dying is not a sad event. It is mostly for those being left behind, otherwise it is a positive passage of our spirits choosing. Own it and embrace it as a welcome 'birthdate'.
Life is the process of letting go.
You will not 'die' before you are ready to go. Be very most loving to yourself. Invite the spirits of those loved and gone before you. Know tears are human liquid prayers. Peace be with you.
