I have been diagnosed with depression in the past, so it's not terribly surprising to me when "My life is worth living" is considered a foundational belief, that has it's confidence fade in and out quite a lot. In this case, the drugs would actually restore me back to a more normal level.

Although, considering the frequency with which it is still happening, I may want to reconsult with my Doctor. Saying "I have been diagnosed with mental health problems, and I'm on pills, but really, I still have some pretty bad mental health problems." pattern matches rather well to "Perhaps I should ask my Doctor about updating those pills."
