Parent loss grief support

On FB I've joined a support group for those who have lost a parent and it's so helpful. And sad to read other people's heartbreaks.
One woman lost her father and gave him CPR for 20 minutes but he still died last Feb and she feels alone and guilty.
I wrote this as my reply
"My Mom died 2 weeks ago and I was with her at the end. There's a quote that sums up how we feel "if love could have saved you, you would've lived forever" so know we are but fragile and insignificant human beings, mortally flawed but our hearts knows no bounds. Someone wrote the day after my Mom died "grief is love with no where else to go" so know that yours and my grief is just like our hearts with no limits. May you find some comfort with your friends and love ones and vent here anytime. Gentle hugs"
I've been gliding video msgs with friends and am blessed with a great job and co worker support system. Being in this FB grief support group helps me to realize that I am not alone with my grief. And that compared to some who have no one, I am lucky to have so many friends and family that loves me and keeps me from falling to my knees and giving up.
