In a particular episode of The Big Bang Theory, Sheldon shows Amy how along the years he has hoarded every single thing he has ever encountered or used in life (basically from the past like books, games, PCs).
I believe this is OCD, but I wanted to know the particular name of the OCD. Searching online I have encountered, "Compulsive Hoarding," but it seems too generic given that it is from the point of view in hoarding everything not essential items from the past.
"Compulsive Hoarding" is more of hoarding everything and not essentials from the past.
If anyone could help me with this.
