Man, only stutterers know the amount of anxiety we go through every single day. I don't know how my heart is still healthy, but I got some gastrointestinal problems due to this great amount of anxiety daily, throughout my whole life lol. I'm 27 now, and today my bowls seem to be driven by the mad hatter, I couldn't poop properly for the past two years of my life, it ranges between diarrhea or nothing coming out at all. Sorry about sharing too much lol, it's just a friendly warning though, just try to let go sometimes dude, if you know you have to speak that's it, you HAVE to speak, it's inevitable, so don't suffer too much before it, just suffer during it. It is easy to say, but I know it's hard, try meditation and, I know that sounds cliche, but hit the gym everyday as hard as you can, you'll see major improvements after some time. Last thing, try to reduce some inducing anxiety habits, like, too much porn, too much social media, cigs, alcohol and stay hydrated. Bye
