Out of Control Defense Mechanism

Besides having a tic people have mentioned certain looks I give them but not specifically what it is. I have never seen the looks in the mirror but I am guessing I am glaring angrily at them at times and my eyes also look in weird manners into peoples eyes. When I sense I am looking at people this way(they often looked scared) I look away and try to adjust my eyes by closing them and trying to look with a softer look. It doesn't always work. I wonder what is causing this. I don't know if it is another OCD thing but don't know how to classify this one. I don't intentionally do it and don't want to scare people. I don't seem to do it to everyone. It happens a lot and way more than the tic does. I don't know the answer to this. I feel like a big meany. Any ideas about this?

Try some meditation mind for healing .Search on google or yt healing meditation for calm mind and soul this helped me

My sons used to tell me that I looked angry a lot when we were talking, which I wasn't. (well, of course there were certain times when I was). Think it is just what my face does when I am concentrating/focusing on what someone was saying. lol, I guess you could try crossing your eyes or something whenever someone looks scared...be interesting to see what their reaction to that would be.

Try chewing gum. I have a habit of silently mouthing my thoughts and am terrified of doing this in public. I always keep gum on hand just in case.

I have a similar problem.
My family and I have laughingly come to refer to it as 'Resting ****** Face'.
I can be totally Zenned out, at peace with the world, and apparently still look like I am actively seeking someone to murder.

I am currently working on smiling more, and making less eye contact. I am a very intense person by nature, and tend to make aggressive levels of eye contact without realizing it. I discovered both of these while taking an 'Interpersonal skills' course for work.

You might consider making a study of body language, your own and others.
Best of luck, I know how frustrating this kind of problem is.

I, too, have been working on making less eye contact and do try to smile.
