Why Are Saints Joseph and Dymphna Both on My Medal?

I looked online and found that the medal in question features St. Joseph the Worker and St. Dymphna. St. Joseph the Worker is generally invoked for employment concerns, and St. Dymphna is generally invoked for mental health issues. While I could not find an explanation offered for this choice, it is possible that the medal is offered as a means of encouraging those who are undergoing anxiety (St. Dymphna’s patrongage) in their particular employment circumstances (St. Joseph’s patronage).
