Our subconscious probably can't tell the difference between real people and people on TV. The actors in movies/shows never look at the camera so they appear to our subconscious that they are ignoring us, but the people in ads often do look directly at the camera, so when people in ads tell us to buy something we pay attention and are more likely to do what they say.
My advice is if you feel lonely or depressed turn off your TV. If you are depressed watching people ignore you all day will not help you. I suggest you go help a real person. We desperately need each other, both to feel useful and needed. Taking drugs to help with your depression won't help anyone but the pharmaceutical corporation.
TV is nothing but intravenous corporatist propaganda, please avoid it as much as possible.
