Emotions experienced chart - that is insightful and matches my anecdata.

I think you get bad emotions when you have high expectations about social media and it is your main source of social life. Where positive happen when you have low expectations about social media and it is just addon to your life.

Example of gaps is being lonely, low self esteem, low self worth, no work network, no business network. So you stay glued to FB to build your life, to keep online friends, because you may have not many in life. Or you have no real work network so you need to stay current on LI because your next job is there.
