@Niralam That depends. If you live normal happy life - good for you, genuinely. And of course reading what you like will uplift your mood. But to go as far as to call it a cure to depression - I put my doubt on that one.
What I've seen is growth of angst, sometimes anger when fail to feel the need and defenciveness like calling people judgemental or feeling personally attacked, taking offence over nothing. True, uplifting things can cause anger, but sometimes it can shake people up. Feeling full spectrum of emotions is really good for person wellbeing.
