I'm sorry, but this is such an extreme example. You should not overdo anything, be it meditation, gaming, playing, reading, any sport, even drugs. Drugs also give you a state of mind that, when taken to the extreme, can harm your social life and well-being. That is not a problem specifically of meditation.

You can safely do anything up to the point that it benefits you. The moment your well-being suffers, or you neglect important parts of life, like friendship, you should stop.
