Hoarding/unorganized vs. Collecting and organized

When does collecting become hoarding?  

I Have to say that I don't know...although I'm not a completely a hoarder...just collecting a lot and unable to organize due to unforseen circumstances.

This week Ì had 2 people help me start cleaning my lego room.  I pointed out what was trash and what was donate. 

In the past, I had so many plans to make a cool diorama with using slot car track for roads...Lionel train tracks for trains until I got real lego track...etc...

Now I'm unable to set this up so I pitched the track. Instead, now  I want to use pure legos for a diorama instead.  The problem is that I planned to sort the legos but now I'm stuck with containers that look like bulk lego.  I cannot get to sort the multiple containers.

Here's my dilemma in pics.  Before and below is a pic of containers on floor and random sorted legos.

Above empty sterilite and other huge unsorted lego

After 3 hours my family helped clean up this mess in pic above since I cannot help lift.

Now I can get help to get things on higher shelves easier.

Sometimes I'm happy with all my legos but at other times I'm unsure if it is hoarding...!

I'd be curious to know if anyone else has experienced the same issue of trouble getting a hold on a lot of unsorted lego and empty containers/full containers.
