These are two of a small selection of words ending in '-ing' and '-ed' that are adjectives, not verbs. Yes they are related, but the ones ending in '-ing' are used to speak about people's characteristics. The '-ed' ending adjectives are used to describe people's feelings or emotions. Here are some others: disgusted ~ disgusting shocked ~ shocking soothed ~ soothing worried ~ worrying overwhelmed ~ overwhelming insulted ~ insulting confused ~ confusing inspired ~ inspiring bored ~ boring embarrassed ~ embarrassing

Another way of thinking of it, is that something that is xxxing will make you xxxed.
