Mentally and physically to make sure I don't do anything stupid or that can cause me to feel embarrassed? Its mentally draining and im anxious all the time. Is this normal ? How can I stop this I didn't use to be this way at all and it's interfering with my relationships with others and having a negative impact on my life.

Another thing you can do is imagine yourself doing something really embarrassing. Picture your reaction and others' reactions. How bad could it be, realistically? Watch other people when they do something embarrassing, and see how they accept it and move on.
Embarrassment is tough because it gives you a freeze moment. If you think about that moment you'll get hung up on it. You need to remember that after that moment, things pretty much go back to normal. So when you imagine yourself doing something embarrassing, keep imagining it. People don't stand around in a circle pointing and laughing like they do in the movies. Even if you do something embarrassing and people notice, in about three seconds they've moved on to something else. So what you really want to get to isn't living a life without doing anything embarrassing; it's living a life where you roll with it after you mess up.
