I deleted all my social media accounts many years ago. It was only bringing me back to my inabilities to connect, to be happy and to be liked by others. Even though people only publish on social media the things they want others to see (as some have already stated above), they still had at least those moments to share where they were seemingly happy. Me, I had no such moment to share and I felt very guilty about it. It became clear that I didn't want people to see anything about my life, because there was nothing appealing about it. Therefore I removed all my accounts (which arguably made me even less likely to connect, make friends, and experience such moments of apparent happiness, but also less likely to be betrayed, mistreated, or mocked at).
Also, people publishing photographs of me was constantly reminding me how ugly and awkward I am in comparison to others. Contrary to OP, it's not much that it was enraging me seeing others be happy (I didn't care much TBH), it's more like it was making it clear that there was something wrong with me. So I dodged, as I always do.
