My stutter is so bad right now

My stutter is so bad right now stopped consuming caffeine, started exercising and counting calories to make myself feel more confident but it feels like my stutter has become worst. Can it be because I'm adjusting to new things? I also just moved across the country and I know my stress level is a little high but I feel like everything is giving me a opposite result to what I'm trying to accomplish... Any suggestion or advice would be extremely helpful and appreciated! 😪
