I think @Midsomer captures it best and her post is very astute
Grieving is lonely
@glitteryboots. I felt sad re as img your post. A month is a mere blip in knowing someone all your life, a parent, Let this woman without judging grieve how she feels she will get through it. She's not asking for your opinion as to how appropriate you think she's being. You should unfollow if it triggers your feelings about grief.
If it's not for you, to grieve that way, then that's ok, you obviously had similar painful losses and it's be awful, really unkind if any of those friends who you spoke to in midst of depth of your grief were secretly judging you for 'making a production out of it' when you weren't , you were just surviving.
My sister died over 2 years ago, i still feel floored by her loss. I wish I could find a way, any way, to make it feel better when the periodic grief tidal wave overwhelmingly hits. It came multiple times a day for months on end. I barely remember time passing. So if getting attention on fb works for that lady, well ... good. Ps. My dad is 80, if or when he dies I will be equally devastated but perhaps less angry about it, maybe not, as He's my rock.
