Perhaps you are sensitive to people seemingly giving you advice, because you aren’t seeking it, nor do you desire to change? Not trying to put words in your mouth, but I think you might be interpreting the recommendations as directed at you. Do you suspect that their advice may have a kernel of truth, and you are reacting to the person who caused your internal self to recoil against change? Just food for thought, not directed at you personally.

Maybe that says more about you than them. You're on a social website right now, engaging with people voluntarily, but you're insisting you're only happy by not connecting with people?

Some things that make people happy are things that are bad for them. Those aren't mutually exclusive categories.
