I’ve noticed that sometimes stutters are just really hard. Other days it’s not even a thing. The fact that you kept trying is really impressive. You have some pretty great perseverance. Off topic, kind of, have you ever heard of Camp SAY? Check them out - they do scholarships too for financial assistance to get you there. I believe it’s the last couple of weeks of July in San Antonio, TX. Lots of teenagers who all have varying degrees of stutters. It’s a pretty great experience.
