I'm thinking of lying about being depressed
Do you want people to believe you are depressed?
Yes, I don't have any emotional problems.
You should not lie about the state of your mental health to get attention from others. Instead, you should interact with people honestly and appreciate your health.
Yeah yeah, I'm just going to learn it online and pretend to be depressed.
You should not fake having depression, there are people with real issues who need help and you are making their struggle unbelievable. Please seek mental help if you really insist on doing this because it just ain't right.
