My stutter can be the same some times, I think it’s due to you being really comfortable around friends and family so you don’t think about stuttering as much compared to when you talk to a stranger. When talking to a stranger you focus on what you’re going to say to make sure you don’t stutter however when talking to family and friends it comes out naturally which may be why you only stutter around them. I hope everything goes okay and you’re friends and family won’t care if you stutter, stay safe 🙂
