Serotonin (the neurotransmitter which most anti-depressants act on) is found in all bilateral animals including worms and insects. Therefore I think it’s likely that virtually all of these organisms can experience some form of depression/serotonin imbalance.

There is research that shows that some lobsters will lose the courage to fight other lobsters, but when they are injected with serotonin they will regain the courage to fight. Many interpret this as evidence that even organisms as simple as lobsters can become depressed. (https://doi.org/10.1073/pnas.94.11.5939)
