People I know and I'm friends with do that for me sometimes (finish my sentences) when they see I'm really struggling. Sometimes they take several attempts at what I wanted to say, but other than that, I feel like it makes things easier for me due to the way I stutter (I get stuck on the first letter and it takes a while to spit it out. Sometimes it really takes a while, depending on the day). I joined the sub recently and I don't know any people IRL that stutter, so I just assumed people who stutter wouldn't have an issue that others finish their sentences for them. They look like they don't mean to mock me and genuinely want to help me out. Sending you my support and I hope everything turns out okay for you.
