I just can't get to sleep

I'm not going to post this straight away. But I can't sleep.
I've let someone I care tremendously about know this blog exists and he's reading it.

I can't get to sleep for all sorts of reasons but it started because I drank too much and I miss my brother.
My daughter was asking about him today.
I can't know him anymore. He's almost been dead as long as he was alive but as his little sister, well, that passed long ago.
He knew me before I knew me.
He'd seen and understood what my feet were long before I stood on them.
He shaped me without intending to. He was my big brother.

I wonder if I seek that gap out.

And I'm sad. I miss who he could have been.
