even if u successfully hide your stuttering the next time, it'll be back. Embrace it, people don't really care that we stutter, yes they find it funny but trust me no one actually cares. I self isolated the last 2 years because i had some problems and one of them is being so self-aware of my stammering. When i finally got out of my comfort zone i asked people around me if my stuttering is bad and most of em no and even if it is they just don't care, everytime i stutter in front of them we just have a little laugh about it and justt keep going. If she likes u, she won't care.
