rather than try to speculate , here's a google search on it. See if anything is similar to what you are feeling. Actually i think selegeline, or Eldepryl, which is the forerunner of Azilect , has anti-depressant effects . Don't know if that applies to rasagaline.

is that the only med you are taking?
best wishes,
