Hoarding is when it's really hard to throw away or give away things, even if they don't seem useful to others.

You might feel like you need to keep them "just in case," and letting go causes a lot of stress or sadness.

Over time, this can lead to rooms full of stuff, making it tough to use your space normally.[1] [2]

Collecting lots of items like papers, clothes, or junk mail that pile up.

Clutter that blocks walkways, counters, or beds.

It might start small but grow over years, affecting your daily routine.

If you notice these, it could be hoarding disorder, which is a real mental health condition, not just being "messy."[3]

Feeling upset or anxious when trying to get rid of things.

Avoiding having people over because of the mess.

Hoarding can come from a mix of things, like family history (genetics), brain differences that make decision-making hard, or tough life events like losing a loved one or trauma.

It's often linked to anxiety, depression, or OCD (obsessive-compulsive disorder). Sometimes, it starts as a way to feel safe or in control.[4] [5]
