I can understand ! I mean tbh I can’t comment on what your sister doing ! She’s living her life ! May be that’s what she wants or she knows what she’s doing.. Your parents are a bit conservative so may be u can relax and try talking to them but you’re doing fine ! If you can’t find someone I guess then you have to wait for that person ! Try relaxing , your stuttering gets better ! I can’t speak a word when I’m nervous or anxious ! Try to be calm while facing things ! I have quite developed a don’t care attitude and it actually helps in life and my speech ! Take care ! 🌸
