mini-vent and a question about stuttering.

mini-vent and a question about stuttering. this is kinda messy, cause im not putting too much thought into writing this, sorry! is it just me, or does speaking to people who dislike stuttering cause me to stutter more? i stutter less with my friends who honestly don't give a crap about my stutter; contrasting to me with my mother, who gives me a disappointed stare whenever i stutter, then tells me to go to therapy harshly. with my friends, i stutter only slightly about every 5 minutes?? whereas with my mother, i have difficulty getting my feelings across, even to the simplest "and" or "when" or "you." now that i'm done my mini-vent-thing, now for my question. does anyone else experience this? cause whenever i hear the word "stutter" it doesnt come to mind. when i start off a sentence, sometimes i open my mouth and form the word, but the sound doesn't come out! so im just left with the sound "aaaa" awkwardly opening my mouth, unable to complete the word. then i keep on doing it or try to beat around the bush, but it never works! i play piano, but sometimes the STUTTERING GETS TO MY PIANO PLAYING TOO!! as in, i start off the song, then I press the same note over and over; its confusing.
