Few years back, I have been diagnosed with hypothyroidism, but then it was treated well. Tested again and the result came out negative. However, when I speak, people think I'm angry and the listener doesn't find my tone polite. Although I try my best to conversate at the politest level, the problem seems to be increasing day by day. Then I stopped talking. But you know sometimes you really want to speak things out. Some people always remind me of my tone. Believe me, it's unbearable now. Does anyone experience the same thing? Any thoughts? Will appreciate. Thanks.
