Regarding all the depressive posts, how much of them are real and how much of them are written for attention/karma farming?

Recently depressive posts about life are getting so prevalant on my feed and I read them a bit, people are talking about their failed academic life, carrere, economic situation , friendships, loneliness.. Ofcourse these are all problems and nearly everyone have at least one of them, but seems like people who write those posts and comments have all of them.

It seems so unrealistic. In real life I know tons of academically /professionaly succesfull people who have hard time socializing, there are people who are great at making friends but stay poor, attractive people who are lonely and etc.. I don't think life is this much depressive. Everyone is different after all
