The Framework For Tackling Avoidance
Spend 20 Minutes Per Day Focusing On Grief
By scheduling time this way you are containing or compartmentalizing your grief.
And although it may be painful to focus like this, it can make you feel better because you've set aside and dedicated some time for them.
It's also sending a clear message to your brain that grieving is important and that you're not neglecting your feelings.
In time you might find that you won't need to carve out so much time.
