Yeah, during puberty mine got a little worst.. now, at almost 30y, I have moments that lasts 4 or 5 days in which it gets really hard, but usually, I’m pretty close to being fluent. A few stutters here and there, but nothing that really bothers me. If my 16 ~ 18y self could know that at the time, that period would be much easier. Don’t let it get to you.. with age, you’ll stop caring so much about it and things will get A LOT easier
