I'm going to ghost my friends
Why would you want to ghost your friends?
It makes me feel like I can conquer the world!
Ghosting your friends shouldn't make you feel like you can conquer the world, it should make you feel bad. Being a good friend is important, and ignoring your friends for no reason isn't the way to be a good friend. If you want to step back for a couple of days, let them know, but don't ignore them.
Nah. I'll just ghost my friends and in a few months I'll come back and join them. I hate being attached to people.
You should really consider what you're saying. Do you really want to be a hermit? Your friends will think you're rude if you just ignore them; you could keep in touch without making your friend feel abandoned.
