where to start...what to do

I have let my griefwork go.
I have been ignoring my writing, I have been wrapping myself up in daily life because I felt it was necessary. I have been obsessing. Again.
My eating got out of control. I was eating a few bites of something once a day. I have not eaten more than once a day in months. I started eating again, bits and pieces, and every time I ate, I was in massive amounts of pain. I was sick. Eating actually made me sick. I am working on it. No eating disorder here btw. I want to eat, I just have NO appetite. It is my usual reaction to life events.

I dont know where to start with my writing.

Do I write about going in for an ultrasound - fertility investigation.
About how it felt being in that room, having that u/s, where my last experience involved being told my baby was, in fact, dead.
About how they sent me back out to the waiting room to drink more.
About how there was a mother in there cooing and babbling to her three month old baby...the same age as Caden.
About how she was incessant...about how much pain I was in...about how I wanted to scream.

Do I write about thinking we were going to ttc again...but now we aren't?

Do I write about crying again?
Do I write about how for some reason I have stopped caring so much?
Do I write about how many things I want to do, and how I have no drive to do them?

Do I write about how last night we found out we are going to face a serious, serious financial problem in the next year?
About how I have no idea how we will manage?
About how I feel like I have no options?

I guess I just did...
I feel useless. I feel...I don't even know how I feel.
