You can tell your mother that you love her very much (she will send you a cup of boiled water or a bowl of porridge when she has a cold). In fact, love does not need to be expressed in words. As long as you really love her, she will understand, and then she will take the initiative to talk to you, so that you can answer along, and slowly you will have more languages! What you want to say will become natural! Then there will be no unspeakable "concern"!
