I would strongly recommend this person NOT to take any anti depressants. They are very toxic to the body, especially to the liver. And since I believe that many depressions are clearly linked to toxicity and therefore to the inability of the liver to properly detoxify the blood (which is one of his main functions), taking an anti-depressant would only make things worth in the long term.
I suggest she/he looks into body cleansing, diet change. Colon cleansing and Liver Flushing would be great places to start. But of course it's not a quick fix. If she's really having a hard time, she might try herbs like St John’s wort, Rhodiola and Valerian. Fish oil helps too.
