It's true that we eat a lot more foods that provide harmful fatty acids than we should. Obviously, we should eat healthier fats like omega-3. Along with the studies the others have mentioned. Nations with populations that consume large amounts of seafood and other foods with this fat are showing lower rates of depression and other illnesses.
It is only one study, but it appears that taking Omega 3 fatty acids can potentially be beneficial to people who are depressed. The study indicates that taking these supplements (the subjects took capsules a day of a fish oil supplement) can help as long as the patient does not have anxiety disorders. This is promising since the experiments were done using a double-blind procedure and the results were published in a peer-reviewed journal.

I agree to what the 2nd post has said.
Studies have shown that omega-3 supplements have positive effects in depressed patients. Though, these patients were only depressed, not anxious.
Omega 3 affects brain alchemy and they favor the transmission of neurotransmitters, which are associated with emotional balance and positive emotions.
Omega 3 fatty acids are reducing the risk of stroke and inflammatory diseases.
