Dear Suzanne,
I am unsure if there is a relationship between smoke cessation and worsening depression.
Your worsening depression may be situational or more likely due to the stopping of the elavil. Elavil is a tricyclic antidepresssant, Paxil is a SSRI. When these two medication are adminstered together, there is a synergist effect. Simply, they both increase the effect of each other.
I recommend you discuss your concerns with a p[sychiatrist.
Best Wishes,
