I try to explain this in a structured way, so that you hopefully don't feel too overwhelmed. Feel free to ask if something doesn't make sense.
Lemmy
Lemmy is like e-Mail, there are multiple websites where you can make an account, but you can still communicate/participate with users from other sites. (This is called decentralisation.)
Instance
An instance is a website that you use for logging in to Lemmy. You only need an account on one website to participate (e.g. writing posts/comments) in Lemmy.
So, since you already have an account, that means you already have chosen an instance, it's lemmy.world.
Community
Like users, communities can be created on different instances. There can even be a community with the same name on two different instances.
For example:
These communities can still be accessed on your instance, they are all synced. (With some exceptions which I'm not going into right now.)
How to participate in communities of your instance
How to participate in other instances
So in summary it's the same Aso for communities of your instance, just make sure to always start/login on your instance.
Direct links
Since constructing the URL like described above is quite annoying, Lemmy can use special links that work across all instances. They are as follows:
Apps
There exist many Lemmy apps. They can facilitate things (especially when you want to browse on your phone), but this also means that the look&feel is different. Some step by step guides might not work exactly the same on different apps.
This was extremely helpful. I do apologize for my panic attack and this clears things up for me. I was able to get access and have a better understanding.
