THEY call it Blue Monday - my arse!
I'd say it's more of a dull grey, and the concept of an average mood on a particular day, that we all feel is pure bullshit. Life is amazing on all its days and in all its colours, yes it can feel shit at times, but thats life, problems are inevitable and infinitely solvable. And as for societal averages, they can just do one, I sm not an average.
Don't let anyone tell you how and when you should feel.
Happy Grey Day π€£βοΈ
