Lifelong mild stuttering turned severe for no reason?

Lifelong mild stuttering turned severe for no reason? Hi all! So for as long as I can remember I've had a very very mild stutter (and for that matter much of my family too). Like once in 20 sentences kinda thing, not at all common or noticeable. If you observe it really hard then you could notice it but you'd have to be thinking about stuttering and all the types and all that. So yea that was basically me for the longest time. So even though I knew I had a stutter it was about as low on the spectrum as you could get. But recently I turned 16, and I feel like overall in the past few months but especially the last month, my stutter went from basically nonexistant to very existent. Like in a very short amount of time it like went off a cliff. While before I would only do like uh/ums, nonverbal auditory blocks and some single syllable stutters and very rarely, I do all of the symptoms, auditory and non auditory blocks, single syllables up to like 2 or even 3 or so words, etc. And instead if it being very rarely. Its like every other sentence atleast once or more. And like I could be repeating multiple words like 3 times. Or even with the blocks, like knowing exactly what I wanna say before I say the sentence and then mid sentence I completely forgot it and have to scramble for something else, and stuff like this has happened even to the point that I cant just try different wording like I normally do amd I just cant say what Im tryna say. And ive been at this level for like a few weeks so like between the very low end and this much higher end it must've been a week or something is all. I'm not complaining or ashamed or sad or anything. I kinda find it cute. But if anything it's made me more attached to it and pretty confused on what happened. To my knowledge, for the most part if you had a stutter you developed it as a toddler and then it either stayed the same, improved, or disappeared. And that stuff usually was decided by about 7 yrs old. So why would something I've had at the same level for over a decade change now? It's kinda confusing for me. And other info that may be helpful, I have some anxiety disorders and stuff and this year hasn't been stress free, but overall this has been the best part of my year, if anything stress related were to cause a worse stutter it would've been when I was having alot more difficulties in the summer! Or last year! I'm the happiest I've been overall in over a year, so it's like what, did a decrease cause that? I assume it's just unrelated and coincidence. And honestly this is kinda dumb but I hope other people feel like this. Stutters are cool, I'm attached to mine, and given how quickly I gained a 'noticable' stutter, I'd hate for it to be taken away. Because of how new this level of stutter is and how much I prefer it, ive definitely been obsessing a bit over it in my mind, thinking about it alot, thinking about if Ill stutter in the next sentence or not, etc. If I was at at this level for life I'd be very happy, but if it diminished in severity I wouldn't be as happy. Anyways apologies for any weird formatting, mobile. Merry Christmas and let me know what yall think! Stutterer for life club let's hope haha.
