In my opinion, you are trying to be considerate. However, things happen around you are not always caused by you. And even sometimes you can make a mistake, but these this does not happen for you just to blame yourself. It reminds what needs to be done. And yet, ban does not mean that you are a bad member of community. Think of many people that changed our lifes. For a simple common example, Einstein. He could not keep on studying on his school, actually he got kicked, but that didnt lead him to be farmer. Nowadays, he is considered to be one of the most important people.
I am sorry about what happened to you. Wish you luck
