I don't think that anxiety has something to do with stuttering

I don't think that anxiety has something to do with stuttering This past months I've been experimenting about how to stop stammering, I wasn't satisfied with my experiments though. One of it is making your mouth wide while speaking and I'm surprised it worked. My confidence level was so high at that time and I'm thrilled with energy. Unfortunately it lasts only for a week. I was walking home that day from school, I'm fatigued due to our group work and essay that we did in class. The next day I was walking down the hallway heading direct to my first period. Let's skip the class part since nothing interesting occured. I was in the cafeteria with my friends and we're having our usual conversation. I wasn't into chatty mode and not energized so basically I began stammering even though I'm making my mouth wide while speaking. I stopped doing my technique since I looked ridiculous and my friends are now getting confused looks. That's where I became being self conscious again. I didn't said a word until I got home, speaking in front of the mirror doing my technique but it didn't worked. I got all frustrated that day. About a week ago, I was fluent and I experimented on that. I noticed that whenever I'm speaking fluently, I'm always energetic, full of confidence, I always smile, being chatty and not giving a d!mn about being self-conscious. My energy level was way beyond, It feels like a can own the whole world. Then all of the sudden, I got bored, tired and being in a state of not being active anymore. Chatty mode drops. That's where I began to stutter. So I don't think that stuttering has something to do with anxiety. Even though I'm with someone that I'm 101% relaxed and comfortable with, even I'm just alone in my room talking to myself I still stutter no matter what I do. Meditations, calming and breathing exercises never worked. But once I get myself thrilled with energy, confidence and didn't care about what people think of me I don't. In my worst days of stammering yes I do still stutter but it reduces it in a great amount, as long as I can express my thoughts well IDGAF.
