If it's really your anxiety that is causing issues (anxiety aggravates the stutter), then there's hope! Work on changing your mindset about your anxiety. Everytime you get anxious about talking to someone, think of it as 'excitement'. Anxiety has exactly the same physical and neurological responses in your body as when you're excited. However we tend to frame it in a negative way. Think of the time when you're getting ready to ride a roller coaster, or when you notice your crush staring at you. The heart palpitations, the sweaty palms, the dry throat, shaky legs, etc are all symptoms of your body getting ready to get you moving. So, the first step in your journey is to realize that the feeling of anxiety can mostly be a positive thing. It means you've stuff happening in your life that regularly takes you outside your comfort zone and keeps things exciting. Your life isn't stale, and you're actually moving forward and growing. Once you stop associating negative connotation to anxiety, then you can gradually start putting yourself in those situations that used to be scary. This is better because now you're doing it in your own terms (instead of something being forced to you), and it will give you more confidence to tackle even more interactions.
