Yes. The only help I'm seeking is the sort of help that helps me grind for more gear sets. No, I dont have a problem, I swear...

No, not any more at least.

I used to try and keep all the dungeon sets with best traits but since transmutation it's easy to gear up a dungeon set. I mostly now just hold onto Maelstrom/Master weapons and gold jewellery.

i'm a hoarder in eso, i'm a hoarder in real life, although i prefer " collector"

storage containers,full
5 mules,full,rest 10 have their inventory half full with maps and surveys
5 houses maxed,im now decorating Exorcised coven cottage
bank,half empty,cause i sold all doubles motifs and recipes ,rest storage but im adding new items every day
decon all double,sold purple rings,neck
thank god i got craft bag for mats

Sorta maybe... I toss a lot but I keep a lot of rarer items that, if I thought about it, I'd probably realize I'll never use

Severe OCD; hoarding is part of it
far worse out of game than in it, but have a full bank and a bunch of storage chests
getting help -- medications and therapy

Don’t forget breaking. Never know which sets 15% chance to proc every 10 seconds is going to turn into a 100% with no cooldown.

There is way to much crafting materials and so little space to store all of it and it would help if u could store materials in the bank and when I pick out up it goes to the bank

None of my character has more than 80/200 inventory, most of them have only 50-60, since they only carry their gear sets, a few stacks of consumables - food/drinks, potions, soul gems, lock-picks - and in some cases also 2-3 gear pieces crafted for research so I can start as soon as the previous slot(s) are freed up. This way I only need to go to the NPC merchant, bank, crafting station to deconstruct every few hours and can enjoy more time actually playing instead of managing the inventory.

I usually sell/deconstruct everything, unless it's a gear piece I need immediately, or I may need for one of my 1st or 2nd line characters. I kept quite a large selection of gear I had acquired over they years, and now it's taking about 750 slots across 4 characters, but I really don't feel pressure there; probably around 1/3 will be broken down over the next few months because the sets turned out not to be very useful, and don't have the potential to become so. Also even if the sets are good, or at least interesting, some slots are useless - for example I have no use for bows from stamina sets since I have plenty of Maelstrom ones and I can farm Master even easier (higher chance for it to drop to one or more out of 4 people). Another reason is how I group the gear on my chars: a "top" a "bottom" and a monster set, in such a way that I can use almost any combo of = 2 x 5 piece sets + monster set (full or half) on any character, so the "top" pieces from a set I use as "bottom" are no longer necessary.

I recently started selling low level materials that had accumulated in my craft bag from the daily writs. I also sell every cooking recipe, furnishing or furnishing blueprint that has already picked up by my master crafter, and it's worth selling; otherwise I learn it on one of the other chars - really no point in selling the common blue recipes or green furnishing blueprints that are worth around 100 gold. At this moment about half of my bank is taken up by surveys and treasure maps, and I also have a lot of master writs stored on several chars. But this is not hoarding for the sake of hoarding, but rather I've come to the conclusion that those are more efficiently done in bulk. For example picking up multiples of the same surveys takes less time, since you just ride 50 m away and return when it resets until the stack is exhausted, and picking all surveys and maps from a given zone is more time efficient than going after each. Also pre-crafting consumable writs in bulk and turning them in in short order takes considerably less than traveling back and forth to the crafting station for each; even more so for the gear ones, even if the stations are all grouped in the guild hall, since porting takes time.
