Does anyone else tend to reply super fast, like immediately, when asked a question?

Does anyone else tend to reply super fast, like immediately, when asked a question? I take language lessons and my teacher who knows I stutter has noticed several thing as my stutter which has gotten substantially worse lately. One thing she’s noticed is that I will tend to reply to her questions straight away. She also said that some of her students, unlike me, are comfortable with her waiting 30 secs in complete silence sometimes up to 1 min to formulate a quality answer. She said she thinks the reason is that I feel the need to want to say everything and get lots of speaking time.. and so I told her ‘no, it’s bc I don’t want the other person to wait… I feel like I’ll be wasting their time’ but I think deep down, I knew the reason.. I hate being the ‘spotlight’, I hate having the other person’s eyes on me while I stutter or fumble on my response. So I’d rather just blurt out a very short response immediately just in case I stutter or block. Like before the freeze response hits. My sentences are always probably no longer than 5 words. I am trying to think and formulate and change this habit but it seems like I’ll automatically freeze/be the deer in the headlights and panic. My brain will go a 100 km an hour to think of a good reply but my mouth won’t cooperate and my mouth feels paralysed. This is somewhat a cycle. Now I don’t know it’s bc I stutter or bc of this freeze response that is really the root.. anyone have any thoughts?
