I don’t know how to have conversations,tell stories,jokes, talk in complete sentences and it’s really ruined my personality. I really don’t, because I’ve stuttered my whole life early on I was able to control it and have conversations and I made a lot of friends but now I’m just unable to. And I don’t know how to hold a conversation or even have one. I can’t ever tell a funny story or anything longer then 2 sentences. I love debating and arguing but I can’t join the debate team in school. But my problem is, I want to have these conversations with people and laugh and tell funny stories but because I have no practice at it first of all and second of all I’m incapable of it because of my stutter I’ve become somewhat anti social. And sometimes I come across as rude,mean,cold,etc when everyone’s laughing and I just stay there in silence, my own family sees me as somewhat weird even though they understand I have a stutter they always sit there laugh and joke and I’m just there in silence and when I do talk it’s just small things like “what time is it” or “what are we eating” like I was even told “your just kinda weird” by one of my siblings and none of my aunts or uncles even have a relationship with me besides hi and bye. In school I’m able to somewhat make friends but I’m incapable of talking to girls like 0 percent chance. Because it’s not that I stutter but I don’t know how to hold a convo with them or make them laugh bc I’ve avoided it my whole life and when I try I stutter. Like besides helping me out with my stutter how can I just learn to somewhat have a conversation Bc I’m incapable of it.
