Hi. Stuttering is definitely neurological. It’s an ebb and flow thing so you’ll have certain moments where you’re more fluent than others, you’re probably more comfortable at home with your family so you stutter less. But it’s not going anywhere, it’s not curable but there’s nothing wrong with you either. It’s just how God made us, I stutter too. We just speak differently than others but we still have important things to say. Hope this helps! Blessings to you!
