My goodness.
I dont' even know where to begin. My heart breaks for you and your family.
Thankfully - I look at their smiling faces and take a deep breath and I'm thankful that children have more resilience that we do as adults.
We see all that they could have had - and they just look at what is there.
I'm sure at some point - it will hit them very hard - but for now - their smiling faces really cheer me in the midst of your painful struggle.
I hope this all gets sorted sooner rather than later and I really hope that your interview goes well and you can get your family to a place where your joy starts to return.
