well, it's difficul to be a teacher but I can help you to precise what you want to say for exemple
here you just said "I something wrong you can tell me and teach?", the correct sentences would have been : "Is there something wrong that I said that you could tell me about and teach me to correct ?" or "Did I said something wrong that you could tell me about and teach me to correct ?"
but I'm not clever enough to explain you why those words are the one to be chosen...
if you don't understand some things I'm saying you can tell me and I will try to explain it more clearly
