Reigen Depression 

When one hasn’t seen a picture, video, or gif of Reigen from the anime Mob Psycho 100 in such a long period of time, that they become depressed.

Depression 

When you've felt like the world has been against you for so long, that you've become numb to everything.
It's not a joke.

Post Concert Depression 

Also known as PCD, it is the depression after your favorite band or singer's concert. You feel like you miss them a lot even though they don't know you, and you don't know what to do with your life because your life is so boring out side of a concert. Sometimes, symptoms are so bad that you cry a lot, can't eat anything, and don't talk to anyone. A lot of the time you'll be looking at the pictures or videos you took at the concert or watch other people's recordings on YouTube.

Hey, Susie, you look really sad. Didn't you have a good time at the concert you went to last night?

Nah, man, leave her alone. She must be suffering with post concert depression.

Post concert depression 

After seeing your favourite singer(s) play live, you might get PCD, post concert depression. Not cause they weren’t what you were expecting, but cause you saw your idol just a few feet in front of you, and you realise you might never see them again. (Lazy description of it)

Person A: what’s up with B?
Person C: they saw Twenty one pilots yesterday.
Person A: why are they still crying?
Person C: PCD
Person A: what’s that?
Person C: post concert depression.
