With the rise of social media there has been an increasing amount of "information flow" which may cause anxiety. Suppose that you posted a picture or a tweet, facebook post etc. as you become aware of what might other people think there is loss of your true identity. Social media does a good job on showing the good but a terrible job at showing the bad. This imbalance of information leads users to become depressed or anxious. While in this depressed form, users don't post depressing stuff, which adds on to the problem. I think that making it okay to feel like shit without being ridiculed goes a long way. However, social media is wired in the same way as smoking. Except instead of Nicotine it is likes. Any mental disease normalized as result since "everyone has anxiety". You are correct that being yourself is good solution however like a mention most people are afraid to show themselves as their true self because it may give off a less enjoyable experience for their followers. But what do I know haha
