Hey man, I just got done with my first year of college, but I had a similar experience in highschool. I can get major blocks, and starting highschool made them way worse. The biggest thing that helped me was to be more confident (Ik, easier said then done). In terms of practical things to try, I like to say a Spanish word under my breath before I start talking...usual hacer or picar...it some times will he’ll be to get going. In terms of talking to girls, I can relate to you. I got my first two girlfriends by adding them on Snapchat through quick adds (we went to a smaller school so everyone knows of everyone else). I’d snap them on that for quite a while before we ever hung out. This did two things: it gave me confidence since it felt like I already knew her when we did actually hang out, and it allowed her to get to know me first so she wouldn’t immediately judge me for my stutter. This will be a tough time for you just like it was for me...but don’t give up! If you want any other help, please DM me. I’ve never met some one else with my type of stutter!
