Coughing in the bathroom

We recently have had a very severe cold weather throughout America. People arround me catches cold and recovers. Somehow, I have had slight coughing for a while, which persists for quite some time.
In the bathroom, I thought about this. Why my coughing doesn't go for a while? Here's what I got:
Maybe I am not appreciating this coughing enough. Whenever I get sick, I have to appreciate it. Whenever somebody gives me a hard time, I have to appreciate it. Why? It is because I may not deserve such harsh treatment. I may not have done any specific bad things that caused my sickness, or my being hurt by people. However, maybe somebody related to me such as my ancestors may have done something wrong, and that has been causing him/her to have to suffer in the other world. If I receive this attack with grateful mind, then this may help them to be in better situation over there, because I received beatings for them with gratitude.
Therefore, this moment is so important. I do have my free will to choose to be grateful, and if I choose that way, that could help somebody to be in better situation. Of course it is my choice. If I don't choose that way, then basically nothing changes, and I may go through the pain anyway.
When I think that nothing happens by chance, God must be paying attention to how I respond to each moment's happening. I am the one to make that moment shining. This is a chance given to me by God. At leaset I lose nothing by being grateful.
Therefore, the conclusion in the bathroom was that I need to appreciate this coughing more, using this chance to enlarge my mind to care about my ancestors, and care about God.
