Help me im desperate

Help me im desperate Im 13 and i have had a strutting issue since i was 7-8 it wasn’t severe as it is rn but over the years I’ve been having severe strutting issues like moving my hand to the left n right as if it helps me say the word that im trying to say sometimes i hit my self or start screaming to just get the word out and im mentally exhausted I can’t keep doing this anymore so if anyone has some tips to at least make it a bit better I’d really appreciate it
