IDK

IDK I speak fluently with my family and friends (no stutter)....I have no stutter when reading something whether on stage or in private(My mom used to push me participate in speech competitions....won a lot...so i think this is thanks to her). But when I speak with someone I dont know or someone I am not comfortable with....the stutter attacks....Any tips/routines/habits/anything to deal with this? please help...I have to start college from next week and am sure that new interactions will follow
