I can't for the life of me understand why it comes on and off in such random words in the middle of sentences but I do think the severity of it has something to do with our nerves in the sense where like...imagine being alone in the shower talking to yourself, i don't think the majority of us would ever stutter. But there was this homework i did where i read out loud and I didn't think it would be possible for me to stutter because i was alone just reading and yet i did randomly stutter on a few words as i read them. But continuing to read that time was like nothing, I easily got over it and the blocks where no where near as severe. So though I think the stutter is random whether I am reading out loud alone or talking with people (i could talk for a bit and then poof, randomly trip up or feel a block \[Edit: But also I'd find myself blocking hard before starting even, when i'd really excite myself with nerves over say picking up a phone call, just as I picked up I would instantly block and fear them asking if I was there\]) the severity of it I feel I was able to control with time by focusing on NOT thinking about how anyone else around me feels but instead just the message I wanna say like being alone reading out loud (far easier said than done of course and took a lot of conscious effort over time to see the drastic change that it had on me). As an example I remember how I used to stutter pretty consistently with my brother. Couldn't understand why because with others in the family I didn't remotely as much. And I think it was some kind of subconscious pitfall where my mind was just subconsciously remembered the difficulty I had with him before which just ever so slightly quickly brought up that stutter state/tension again every time. But over time as I tried to implement not dwelling on it or not thinking what he thought as I blocked, I got over it and now I don't stutter with him. Over time since I was adamant about no avoiding since I wanted to not care what others thought as I went through blocks, I had subconscious positive re-enforcements as I realized I could get through it and it just got easier and easier over time. Hope that makes some sense. As they say, the mind is a powerful thing and practice makes perfect. I know it's easier said than done but ...well I made this video a few days ago that's a little long winded about what I went through but maybe it can help clarify as well. This is unlisted, not monetized or anything like that and I had posted it earlier here. If you have any questions or would like clarification on anything I'd be glad to help! Wish you all the best!
