Uncontrollable behavior. With time.

Earlier it was all good but now I feel very weird when anybody is around. I am not able to control my facial expressions even if I try to which makes people think I am very annoyed with them. I am not able to stay normal as I usually do when I am alone. It doesn't happen when I talk to people whom I do not know. I am always very awkward with people I know. Since my own behavior is not under my control, it makes me frustrated most of the times. My relationships with people are worsening as they think I am not happy with them which is not the case. Whenever I try to act normal in front of people with extra efforts, I become even more awkward and thinking about it makes me even more uncomfortable. Earlier this used to happen for a few minutes but now the problem has worsened and I feel awkward all day long if anyone is present around me. I am not able to stop it. I fail everytime I try to fake normal facial  expressions. When I am alone, I am normal. All this is getting worse with time.
