What the fck is happening with FB ADS ?

Sup Guys,
I've been in advertising for 4 years, and this is the worst December ever. Normally, this time of year is when I achieve my best revenue and absolutely crush it... but not this time. I don't really know what's happening.

I'm not a beginner in advertising, so I'd like to know if you're experiencing the same thing. Is this a general trend? I'm tired of spending time and money trying everything to make it work. It feels like Facebook is sending me trash traffic, It's so inconsistency... Today I even made 0 sales, it's never happened to me ....
