The situation of the queen will match my lively interest in her

Could anyone explain the meaning of the sentence in blue? Did Catherine mean she hoped the situation of the queen (of the France) would be fine that were in the interests of her ruling? was the express ususal ? Thanks!

When the Third Estate proclaimed itself the National Assembly and Catherine realized that the peasants and the bourgeoisie had been joined by a group of noblemen willing to give up their own political and social privileges, she was astonished. “I cannot believe in the superior talents of cobblers and shoemakers for government and legislation,” she wrote to Grimm. As the weeks went by, astonishment turned to alarm. “It’s a veritable anarchy,” she exclaimed in September 1789. “They are capable of hanging their king from a lamppost!” She was especially concerned about Marie Antoinette. “Above all, I hope that the situation of the queen will match my lively interest in her. Great courage triumphs over great perils. I love her as the dear sister of my best friend, Joseph II, and I admire her courage.… She may be sure that if I can ever be of use to her, I shall do my duty.”
