Stuttering is not that bad thing to have Anxiety make it worst, things you care about in past or mess up in past ,you will find a way to survive with or without it and it too not that bad ,life moves on I didn't know bro, i am too mess up to tell what to do or not. Just keep living, every day it will get easier . And egg come first,like two pre chicken reproduce to produce egg . Don't complex things out, overthinking of future give me anxiety but when that future becomes past and i think about it in my present , it is not that bad ,like we overthink future and curse our past failure self,but when future becomes present you survive it and worry about next future but you survive it again. Life goes on , don't give much weightage to your future because certainly it not bad as you think of it in present .
