@Forthethirdyearinarow87 Welcome ☕come on in. 
What it looks like isn't really what defines hoarding disorder, though the clutter scale pictures have their uses for many. Others with H/D can't relate to them because they're messy and chaotic, which is only one presentation of H/D.
How much difficulty we actually have in parting with things, whether we think want to get rid of them, or think we want to keep them is the real H/D tell.
Many of us with serious attachments to stuff, don't have homes that look like 'traditional hoarding' equally many others do.
Prior to a mad moving in and out for building works situation we're currently in, most people visiting my home wouldn't have been able to spot whats going on.
Surplus of stuff for the size of the place, but mainly all hidden away, organized, clean, tidy, available surfaces, plenty of space.
But it was being achieved by apart from lots of hidden storage solutions at home, and too much time spent on housework, the majority of stuff was just not in the house. No one could live in it there if it was!
Depression and lack of energy can actually be masking H/D and it can also be a direct cause of depression and lack of energy. Others don't have H/D but depression and lack of energy mean their homes present as if they did have chaotic H/D, and H/D strategies can work for them too.
Wherever we're at, everyone on this thread has a close understanding of overwhelming and overwhelmed.
Do you have a plan on tackling things? (it's ok not to have)
@Karatema Also welcome☕and come on in. 
If DH has lots of stuff too, then you may be looking at a bit of a DH issue there.
If you know you have loads and he doesn't, then that may be something to accept. Have you been having conversations about the state of the place, and is the 'rebuilding something' linked to place to put things?
(If you'd rather not say, you don't have to answer any question asked.)
You may want to read what I've posted below to KittyTalbot about storage units. Are you on an 8 weeks half price type deal or similar?
Regarding taking that big bag to recycling and the pile not looking smaller; this is exactly why some of us list what we have got rid off, because no matter what it looks like, we know there must be less. It helps counteract the feelings that it made no difference. Keep doing it, eventually you will start to be able to see it.
Others will be along to confirm this soon enough.
It is always like this at the beginning, and sometimes comes back randomly., That's when being able to check back, or have others point out, what you have actually managed, becomes helpful.
This is something you have to have faith in. Many of us are doing this long term and have been battling very big complex situations, and this is where mutual support is really important. Well done on getting that bag out.⭐You will get more of them out regardless of how you feel right now.
@BlackeyedSusan I have the same issue as BlueSummerBaby with stress over how much time I have left to get to sleep in, stopping me.
Half term is always exhausting but when you're doing what you're doing, it must hit you hard when you stop.
Respect for keeping chipping away at the edges regardless. It all helps keep things under control.
@BlueSummerBaby Aunt is entirely broke, but actually, I so want a PA! 😀
The anything cheap things "just in case" is an interesting idea to think about for when sorting rather than moving units. Because I think those items are now1000's of small items in with other things in boxes, as I've been targeting visible big easy wins.
Congratulations on the charity shop bag.
@TalkToTheHand123 Unless they're unreasonable 'my show house' type people, then knowing people can come in and out and not be shocked, is definitely a thing worth working for!
@KittyTalbot Storage units are such a double edged sword. People (myself and Solo are just two who say it openly here) get trapped through using them, as much as we might also benefit in other ways. Be careful.
General advice is if you haven't managed to sort things in your home, you probably wont then manage to organize time and transport to do it somewhere else, without support, and prices go up really fast. Things go wrong in your life, and often in storage units too.
