Grrr need to vent

Friend asks for words of comfort and support after her chemical pregnancy.

I offer the support as a fellow friend who has experienced loss just months ago (while she did NOTHING to support or acknowledge me after my 10 week miscarriage)

Then she flays me alive on social media 5 minutes later “does anyone actually have any words of wisdom to help through a difficult time instead of words that are USELESS”.

I’m really losing my patience here.

How do I maintain this friendship while not taking her shit personally, actually enjoying my rainbow pregnancy instead of feeling guilty about it, and not losing my other friend who could easily feel like she’s in the middle of this if I ever had the balls to say anything to the friend whose getting out of hand???
