Be open about it up front in interviews. I’m 25 as well and My current job as soon as the interview started I said “I just want to let you guys know I do have a stutter so if I pause or get stuck at a random point just let me work through it and if you miss what I say due to the stutter just ask and I’ll try and repeat myself clearer”. I used to let my stutter limit me a lot and dictate my life and still do on occasion but we gotta learn to say fuck it and stop letting it control us… I wouldn’t try applying to a call centre though lmao
