Hey!! im sorry this is happening to you! I still have the stutter ever now and again, but it gets bad again when I’m stressed. In my experience, if you’re feeling so stressed or anxious that you start to stutter, it might be time for some help. It’s also worth mentioning that it didn’t completely go away and it took anxiety/depression medications and 7 months of intensive outpatient therapy for it to subside. Since you’re too afraid for the doctor, I’d say try your best to reduce stress in your life where you can. I hope things get better for you!
