Grief for a loved one who has passed, regardless of age is something you will all have to learn during your lives.  But please learn to allow the grief to diminish over the years.  Grieving for a loved one continually does not allow you to grow or for them to develop further for they too are grieving for you.  By holding on to that grief, that sorrow, this is tearing you apart and your loved one also grieves.  The pain will never go but it will lessen if you allow it and be sure that you will meet them again for they are always around you sending their love for they are close to you as a breath.  They are safe and will greet you with open arms when you once more meet with them in the spirit world.  Be at peace dear loved ones.
