I really enjoyed reading this post! You mention some very good points in justifying how great social media can be. What I make of your story is that the idea of being self-aware online is very important. Whether the contetn you are searching for is happy or challenging, we must continue to srtive for balance in ensuring that we do not receive too much of one sort of content. We are fairly good at doing this in real life, but with the help of filter bubbles and more, doing this online is much more difficult. Being proactive and protecting yourself, as you mention, is definitely the right action to take!
