A few pics and a plan of your space would help understand ur space better to suggest..

You don't have to give up your beloved pink. Pink, brown and grey are doable. I googled pink and grey living room and saw some great pictures. Maybe get a large carpet that pulls out the pink (must match the same shade of pink). Then place your beautiful little pink and cream Kashmir(?) carpet over it. Also pull that same pink into sofa pillows. And a similar pink and brown Tablecloth for the dining table will pull the colours together. Just need to make sure all the pinks are the same shade with small accents/border of the same brown and grey from the sofa. Solid colours or subtle designs will be easier to coordinate than bold dramatic prints. These 2 are not the right shade of pink but you get the idea, I hope. Carpets with tone on tone pattern. A dusty rose on one wall would be nice too.

You need art on the wall and a rug and color! Your first step is to purchase an inspiration piece. That piece will either be a rug or a large piece of wall art. That sets the color palette for pillows chairs windows and walls. Wall color is last. Find out if you can have electricals inside the wall. I am guessing you are not in US and house is solid brick or this is a basement space as it looks quite industrial.

You need to specify what kind of help you need.
