For the past week i've been trying to do some exercises, like for example speaking in front of a mirror very slowly, or reading a book outload, now i've found some good friends in university who are willing to help me exercise my speech with them, like for example i would just try to converse with them for like 20 30 mins or reading something do them out load, because when im alone or sing im good, but when i have to talk to a person i just start to have panic attacks, but i believe that we can overcome this problem, we just have to devote more time into practising and put ourselves in those social challenges that you talked about, i dont know what caused my stuttering because i remember my parents telling me that when i was like 7 or 8 years old, i would be a very talkative person,even more than most kids, but i dont just cannot remember what started it, i would always imagine how my life would have been if i was able to talk normally to people. It's very painful, because the people who try to comfort you never really felt that experince, they just tell you don't think about it or don't overthink it but it's just like not being able to control your own body. i''m sorry if i messed up the grammar, english is not my native language :)
