few different routes here - some people do well with the NSA (national stuttering association) which has free support groups and that social element can help with the anxiety piece. if you want actual fluency techniques from a specialist, Better Speech has stuttering-focused SLPs you can work with over zoom which is convenient for college schedules. there's also ASHA's find a provider tool if you prefer in-person. the hand gestures thing actually helps a lot of people so dont stress that.
