Nine weeks....and darkness descends

I have been surprised by the speed of my mental decline.
Since I opened the floodgates with the last post, and the events leading up to it, things have gone decidedly wonky.
The thoughts are back.
I wasn't going to go into them, but for the sake of honesty, I will detail a few of them.
There is a family portrait taken before baby D that is one of my favourites. It's of the three of us, with Miss T holding onto her daddy and laughing at me.
Before all this, it was a happy family shot, but lately I see her sending a clear message of where she feels safest, and with whom.
And when the health visitor says Baby D's weight gain has slowed and his line on the chart has dropped, I hear: "You're a rubbish mum."
When Miss T's teachers say she is having some issues at preschool, I hear: "You're a rubbish mum."
And when no one responds or is available to respond when I finally issue a plea for help, I hear: "We're bored of your woe."
As I listen to my tears plopping onto my pillow, I can't help but wonder what sound dark red blood would make if I released it from my arm. If I still had the sharp razor blades I used to use, I'm convinced I would have tried it by now. Do they even sell them any more? At this point, I don't want to find out.
At the moment I don't feel part of the real world. I can see it, and I can see that it is me who is wonky, not others.
But even if I scream at the top of my voice that wonky part of my brain does not listen to the reason I still possess. And no one else can hear. It's as if the rational me is sinking underwater in front of everyone but somehow they can't see. And if that part drowns, what is left?
Before anyone starts hunting for a number for the men in white coats, fret not. Help is on its way. I have a doctor's appointment for Thursday, and am trying to squeeze in another therapy session soon.
There are lifejackets. I just have to work out how to reach them.
But in the meantime I need places to go where it's okay to be sad and where someone will distract Miss T while those tears go plop as they land.
