Changes in eating and sleeping, low energy, decreased concentration and decreased pleasure are true for both grief and depression.
How are grief and depression different? Grief can be shared in community. Depression is isolating. Grief is an emotional experience that happens to us. Depression overtakes us and can numb our emotions.
Grief reminds us of what is important and what matters. Depression diminishes the meaning from what once mattered.
Depression often includes suffering from lack of self-love and belief in one’s own significance. Grief is suffering from having lost someone of significance who was loved.
