I see a lot of people who use this website as a social media site kind of overthink things about how other people interact with their content to the point of distress and it makes me a bit sad.

Not getting a lot of diamonds, does everyone hate me?
Getting too many diamonds, am I being stalked?
Etc.

I think it's important to remember that not everyone is using this website as a social media site, but as a content repository instead. They're not looking to make friends, they're looking for content that they want to use in their Minecraft games.
It doesn't necessarily mean your art is bad if it doesn't get a lot of attention, it may just not be something that someone else would personally use. Likewise, a lot of attention could mean you made something with a lot of mass appeal.

I think the social aspects of PMC are great and make it stand out from the other big Minecraft content repositories like Curseforge and Modrinth, but it's important to remember that there are still a lot of people using the site more similarly to a repository and not a social media site like Twitter.

It's natural to feel a little sad when your art doesn't get the attention you want, but please try not to let it cause regular distress to yourself. If you think creating and uploading content to this site or any is negatively effecting your mental health, don't be afraid to take a break or even straight up quit.
