The key to grieving those near and dear to your heart is to chunk it. Only go through as much as you can chew. One biteful at a time.
The good news is: there is support all around you!
Ask your angels to support you during this time. We all have a bunch of angels around us who want to help.
Intentionally asking for the help for grieving purposes: eg. the healing angels, the ones that can help you get up in the morning, the alarm setters, the creative food makers, Hell there are even real estate angels that can hook you up with the perfect place to live if you are looking.
Unemployed angels are everywhere and can totally help when you are alone in this world going through your suffering or cannot find the answers to what you need at this moment.
Giving tasks to the angels is one way to start focusing on the miracles of your everyday life :)
Just realize that you are not alone whether you see them or not. You have so much support around you, it is ridiculous!
