I don't stutter anymore.. but my brain won't believe me

I don't stutter anymore.. but my brain won't believe me Hey fellow stutterers. 18 year old male here. I always had a very moderate stutter. Only noticeable when I got nervous or stressed out. I started to read books out loud and to speak more slowly and now i stutter less than the average "non-stutterer". Yet the insecurity is still there. I'm still anxious about it and my brain keeps telling me it will NEVER go away. Like it's buried deep into my whole being... It gets even worse when I'm about to talk to a girl I really like or to some kind of authority. So essentially the stutter is gone but the anxiety connected to it has stayed. How can I fix this issue you guys? Has it happened to any of you? I'd love your input!
