I am 18 years old i also stutter a lot, but at the end of the fay it is self acceptance, i also didnt had any friends as i moved school in lockdown and my stutter made it even worse i have had many embarrassing momemt, i felt why can every one speak so easily and here i am having difficult pronouncing even a sentence, my social anxiety was at it peak but in the 11th grade i saud fuck it, even if i embarrassed myself i am gonna at least try. Thankfully i have made 4,5 really good friends i try to remain really calm in every situation as it helps reduce my stutters, i gave my ielts exam this year and got overall 7.5 band and recently got my student australia visa. Life is unfair bro but at the end of the day you should be able to at least say i gave my all and live your life as many people are busy dealing with their own shit so try to remain as positive as possible. Hope this help.
