What happens if you get your SD card out of your phone and put it in your PC.
If you still can not add or delete files your SD card is probably corrupted and you have to format is.
If formatting does not solve your problem the SD card is broken and you have to buy a new one.
If you can add and delete files on your SD card if it is in your computer you have a problem with your phone and i would recommend to do a hard reset.
