If you are engaging on social media purely for your own benefit you should stop doing it, else you will enter into vicious circle and will be paralyzed with inaction or anxiety.

1. Social media is good platform to do something inclusively, your objective should only be that.
2. Ignore negative reactions made by others.
3. If they cannot be ignored take them as feedback and move on.

The presence or absence of anyone should not negatively influence your thinking or actions.
