Hi. Most likely depression can be predicted. There was a research done and there are factors that can be noted to be out of the norm. For example language, emotion and general engagement with media. People can present with withdrawing or minimising social activity, or self-attention etc. From my practice in mental health ,these are some of the symptoms patients present with. So I would say maybe Social media may predict mental health issues, but mostly if someone reaches out to dig in what the issues are and possibly advice professional help.

Depression relates to the mental nature ,certain feeling & sometime a phobia . If one gets the depression following the working environment of his action person gets not only depression but a disturbance of his mind .

In case of social media everyone desire to show their ideology & cleverness in their representation & sometime these may create a discussion of different nature with all the type of arguments & such case viewer may get confused. With this I have expressed some years back my general views on depression which I take liberty to submit herewith for your kind perusal

Depression is a state of mind .It is the basic temperament of a person concern.Our activities through our mind carries through our conscious & sub conscious mind because of the even nature of temperament our mind immediately grasp & accepts our emotion sentiment .Besides we know well that as a human being we all have five negative elements .

Initial we should acquire our self training through our conscious mind we have to carry out our own introspection in an impartial manner & he have to in our self study to find the weakness of our mind & with our will power ,determination ,& if necessary by taking the recourse of religion we can certainly come out from the root of depression .

This is my personal opinion
