If you got a powerful fridge magnet… drag that bad boy up and down the wall where you think a stud should be and wait for the magnet to give resistance. A strong enough magnet will catch on the drywall screws… then hope the drywall screws are actually in the studs

My mom passed away almost 10 years ago from brain cancer. From her first symptom to death was 6 months. It was horrible to watch. This disease, in all its forms, is a terrible thing. I hope this helps literally anybody.
