I know exactly how you are feeling! Unfortunately all we can do is wait, and try to move forward best we can. It is incredibly rough, I do believe our timelines are very similar. Today was day 7 of 180 and I cracked. I am not sure quite yet, that it was worth it.
Take it one day at at time, and when that gets to be too much, you break it down to the hours or minutes of the day.
I started working out, and trying to eat healthier. With just a week, it has made a difference. I also try to set three goals for the day, whether that is to go through my daughters clothes, or do a craft project or what have you. It helps keep my mind busy, which helps the time go by a bit faster. The second I have a still moment the minutes turn to days.
You will get through this!
