Post poop depression 

The sadness after a real good poop. Sometimes you poop and its feels like part of you has left and something significant has been lost that can never be brought back. It leaves a feeling on incredible remorse and sadness.

Howard are you doing okay this morning?
I'm okay I just have some post poop depression. It will pass.

I have depression 

You'll probably get it when you see me hating myself so I don't shower for days which makes me even hate myself more, because why shouldn't I shower with depression, why am I resisting to normal hygiene standards? Anyway, if someone says that, just say something like 'yeah' or 'Feel you'. Better than you being too nice and who would write a whole book about why that person shouldn't have depression.

Friend: Hi William
Me: I have depression

Friend: Yeah

Post-meeting depression 

The nostalgic feeling that you experience when you meet your long-distance bestie — that’s post-meeting depression.

The moment you two divide, you may feel like the world’s about to end. But no worries, friend. Distance will be broken. You’re meant to be, no matter what.

«Hey, I just got on the train.»
«You‘re not having post-meeting depression, aren’t you?»
«Doesn’t matter. We’re all under the same sky, after all.»

post-series depression

The immense sadness felt when someone comes to the end of a series especially a long one. This can cause lowkey depression and an overall bitter mood.

After finishing the last season I have serious post-series depression.

Post-Black Widow depression

If someone can't quite realize that Marvel's Black Widow was the last film in the MCU with Scarlett Johansson.

You just don't want to admit it because she was a really big part of the original 6 and now most of them are Dead.

My Post-Black Widow depression is really kicking in after watching the film with my friends.
