***** NOT A TEACHER *****
(1) I am not qualified to answer your question.
(2) I am replying because I thought that you would like it if I pointed out something to you.
(a) You write "I am much appreciated."
(i) May I most respectfully remind you that the meaning of "I am [very] much appreciated" =
You appreciate me very much.
(ii) I believe that you wish to say that you appreciate the help of other people.
(iii) So you might wish to say something like:
I very much appreciate your/the previous answers.
