No, it’s a literal disability by the ADA….all speech impediments are disabilities by the ADA. A disability is anything that negatively affects major aspects in life more than the average person. Since communication is important, and stuttering greatly affects that, it’s a disability because it affects her ability to verbally communicate, and communication is a life skill. She isn’t letting it be a disability, as she didn’t choose to have this. It’s a disability regardless what she does, and it isn’t so simple as “Just think positive!” It’s a neurological disorder. It can’t be cured. And it definitely can’t be cured by just thinking positive. With the way you’re wording it, it sounds like you’re blaming her for her stutter. She literally explained how she feels physical pain and how she can barely talk to anyone or people have problems understanding her. It’s a disability because it disables her, not because she “allows” it. She can’t help it, she can’t control it.
