If Earth's gravity was to suddenly switch direction right now (so earth pushes you away and you fall upwards), how f*cked would you be?

Not drifting into space would require a building which is fixed to the ground. Only underground bunkers would be safe I guess.

but the ground is going up too. everyones dead, world would be ripped unto pieces

Well I’m sat in the living room so I’m good

I’d hit my ceiling which is about 4ft above me and then I’d fall back on my bed if it changed back

Since it’s just under 10 metres per second...I’d break my ceiling fan, break through the ceiling, slam into the strut (likely break bones), the slam into the metal roof...ouch

Literally everyone everywhere would fucking die.

Bedroom ceiling with my blanket. Yeah that’s fine

the world would tear itself apart.
