My symptoms include: Can't concentrate on reading and I want to read a physical book but I hear someone else's voice in my head and I can't concentrate on the words in the book because someone else is talking in my head. (Okay, that is just normal). This is why I put the "read aloud" feature on Microsoft Edge. I have too much energy before my exercise and then I have tons and tons and tons of energy after my workout. (Okay that is really normal) Then, I try to meditate and another symptom is hand and foot tapping. What are the symptoms of these? Is this true? People who are living with selective mutism also have hyperactivity part in ADHD even though they physically can't speak? The last symptom is that I am negative all the time. I already knew that symptom because Jason is negative and he has ADHD. And no I haven't read anything on any website except selectivemutismcenter.org ....
