I've tried being depressed but I couldn't
Tried being depressed? Why would you try to be depressed?
I don't know, I just wanted to know what it was like,
That's a pretty messed up thing to do if I'm going to be blunt. Depression is a real thing and it's so hard for people who have it to deal. Don't make light of something so serious or you're going to regret it when it happens for real or happens to someone you care about.
I don't care I was curious.
If you're curious about an experience you've never had, you can read about it or ask someone who has experienced it. Instead of trying to pretend you're something you're not, it might be easier to learn about it from other people's accounts.
