Both sentences COULD be correct - depends on how you would use it. Do you have a topic/sentence?

Alicia, Someone else has asked your question before. Here is the link to wordreference.com: https://forum.wordreference.com/threads/worth-it-worthy.1260629/ Basically, these words have a similar meaning in some contacts and different meanings in other contexts. That's why Verna was asking for a topic sentence.

Thank you guys for the responses. The sentence would be: Don't let them upset you, it is not worth it / it is not worthy
