2. Let children understand that love is not the whole of their life. You can't ruin your studies and your health just because you are lovelorn. Only by focusing on improving yourself can you meet better yourself and better others.
Don't accuse your daughter of puppy love, and don't accuse her of lovelorn. Learn to help your daughter divert her attention and let her know that lovelorn is not terrible. The terrible thing is to plunge yourself into the abyss of self-doubt.
