My T takes 4 wks every summer. Been with her 10summers. The first yr I after being devastated blocked it out.
Little by little over each yr it changed. Yes we can lose ourselves in activities etc, but the mourning needs to be felt. Then we no longer have to do things to distract from the absence, we begin to use it. Stay connected even in absence.
Just go with whatever comes up for you. It won't be the same every day. Somedays it's easy, others its difficult.
