my galaxy mini gallery can't detect SD card

[hwangmiyoung]

so today i unmounted my SD card and read it on my computer. When i inserted it back in my mini and checked my apps, i lost so many of them. also when i checked gallery, it says "No SD Card detected". I tried to check My Files, and the apps and pics were totally fine and can be read.
I tried to read the sd card in my computer and it's still fine.
is the error in the mini or the card?? and how should i deal with it? i'm not a pro so i need your help
thanks

you might have damaged the connecting pins, please remove the card and look into the sd slot check for bent/broken pins
