Def #1 is way off. Loneliness is to feel that other people don't relate to you; to be misunderstood _can_ create this situation but so does different likes/dislikes, different moral premises, or even plain prejudice.

Def #2 assumes that there's no such thing as non-verbal knowledge. I wouldn't be so sure; if there's one thing that all that qualia crap shows, is that some things cannot be communicated verbally.

>the lack of understanding you by other people is caused by the lack of skills to explain yourself to others,

Even if someone accepts the heavily questionable premises ("definitions") #1 and #2, this is still problematic because it is an unwarranted assumption. It is not a logical consequence of the premises, even if dressed as such.

>Ultimately, you are the recipient of feeling understood or misunderstood, not others. So it’s your task to make others understand you.

GI/GO. Questionable premises + faulty reasoning = dumb "advice".

Some people will never understand you no matter how much you know yourself, and how good you are at explaining yourself to the others. And some people will never relate to you no matter how much they understand you.
