Trying to relate what I'm feeling

So, I've come up with a picture in my head that truly helps put the feelings into words:

Let's pretend that we are at an amazing theme park for the entire day... Lots of excitement, rides to go on, things to experience.  We know that the park has one of the biggest roller coasters in the world and we decide to go get in the queue.

As we're in the queue, we have some nice chatting, fun moments, and we watch over and over the groups of people ahead of us go on the roller coaster.  We've watched it so many times that when we get into the pavilion where the final waiting line is and we can't see the coaster anymore, we know exactly what that first hill and drop looks like.  We are anticipating our turn.  But we there is also a strange bond with the group that goes ahead of you through the little mini lines at each train seat.  As they sit down and look up, you're smiling a thrilling smile - kind of sending them off - saying we'll be right after you!  A big air blast and then their cars start forward.  There's a feeling so clear in that pavilion - we're all sharing in the thrill.  Even though, we haven't even gotten in our own seats yet.

Watching the people ahead of you climbing up, up, up, knowing they are going to peak and then have a rush of adrenaline kind of makes you have the adrenaline already start pumping in your own body.  It's the anticipation.

There are families who just got their travel approval just a few days ago and are already in China!  I feel like I'm standing in line watching the thrill of a lifetime happen before me and getting geared up for my own rush.

I enjoy seeing others experience it.  I love the joy of the anticipation.  (On a side, I'm not big into roller coasters, or adrenaline rushes.)  But I feel like it's coming and it's going to be the adrenaline rush of a lifetime.  Getting the call that we have been approved to travel... it will be unreal!

Buckling my seat belt on the plane heading to China... it will be intense!

Trying to sleep the night before we meet Sammy - knowing it's his last sleep as an orphan - it will be out of this world!

Feeling Sammy's cheek against mine - I cannot even imagine!

Normally, saying you're on a roller coaster or anticipating a roller coaster has negative connotations.  The up and down and up and down of emotions is usually what it's referring to.  But it's the only thing I can come up with to make sense of this strange sense of excitement and anticipation.  It's like we're standing in the queue line and just enjoying the hot sun, and watching the thrill of others.  It's amazing!

We feel like things are going to happen fast.  I think we won't hear anything for a month at least - but that might just me trying to keep myself in check.  But there's just this sense - this overwhelming settled-ness - that we are in the midst of a miracle.
