I stutter more when I am relaxed :/

I stutter more when I am relaxed :/ While many people tend to stutter less when they are relaxed (including a person I personally know), I stutter more when I am relaxed. I have noticed that when I am uncomfortable with someone or angry at someone or want to show someone a lesson or somewith with lower authority than me, I stutter less. It really sucks when I stutter in front of people who know I stutter or when I am relaxed. Weird.
