This resonates with something I felt deeply as a kid and which stayed with me for a long time, into my early adulthood.

But you can't actually guarantee that others will understand you, no matter how good you become at explaining yourself. At the same time, acceptance and even connection on the basis of imperfect understanding is very much possible— connection of a kind that is still deep and meaningful, and which abates loneliness.

There is definitely some truth to OP, though. Feeling understood and correctly recognized absolutely does help with loneliness. I hope most people don't see their loneliness as a burden or personal failing, that they wouldn't have if only they were a perfect communicator.
