Aye, social media would have you thinking that everyone else is having a ball of a time, always on holiday, always at a party, always looking their best, always eating the best food etc etc. If you were depressed before looking at it, it would probably only make it worse.
But as the psychiatrist in one of the interviews I posted said, social media doesn't show you people waking with a hangover, or sick with a cold, or doing the ordinary things of life like shopping, or working a job you dont like to pay the bills etc.
