I step on the drywall above my kitchen and it cracked all the way thru and ran for about 3 feet and now you can see where that cracked area is. I put spackle in crack but you can see where the ceilng is lower.
do i have to replace the drywall or how can I push the ceiling back up even with the rest of the ceiling?
you will probably need to cut out the area between the 2x material and then put \in a new piece. add nailers to the 2x so you have something to screw the piece to. then tape and use drywall mud couple of coats and sand and prime then paint. this is the correct way to do it.
otherwise it will crack and never look right.
