Is Stuttereing psychological or neurological Like some people claim Stuttereing can be cure ,some say it can be control to a level it can't be noticed,some say it is just a bad habit and some says it is neurological it can't be cure,we have to accept it and learn to live with it . Some says therapy or online program help them in there Stuttereing while other shit on same program and says nothing could change their stutter. Some says talking to stranger or speaking in public help them while other says it make their anxiety worse. Some control their Stutter as they become adult while other stutter become worse when they become adult. Some acquired their Stutter in their early to middle childhood while some have it as long as they could remember. But what we say Most of us are depressed with our Stuttereing,it make us half as a individual,it difficult for us to live without crutches and especially when we become adult ,we have to do everything ourselves,it too much stressful. I tell you my story,i am 18, i am away from home for college, i don't have any friend both online and offline, i sit alone in every meal of the day,i am doing journalism course,my parents are stressing me out that i gonna ruin my life because of it and i have to shift my pg so i have to go out may be tomorrow to search for good place on my own and there is lot of talking and negotiating there, if i gonna ruin it my parents gonna give me piece of their mind ,i too gonna cuused myself.And i am overstressed and i do self destructive things when i am overstressed. Fk it It kind of seem years when i was happy i am doing everything like visiting monuments, stand up shows but i couldn't find happiness anywhere.
