Most present and past participle forms of verbs that describe emotion or feelings can be used as adjectives, but the meanings of the participles are not the same. For example:
A fresh ocean breeze on a hot summer day is refreshing, so I feel refreshed.
The present participle (-ing form of the verb) refers to something or somebody that causes the feeling:
The breeze is refreshing. (The breeze causes this feeling.)
The past participle (-ed form of the verb) is used to express how a person is affected by something.
I feel refreshed. (I am experiencing this feeling as a result of the breeze.)
Note that you cannot use the past participle/–ed form with things because things do not have emotions.
