Buddy, I know this feel. I'm in 3rd year of my B.E. & in 5 days there's a presentation & I know, I will suck because of these fucking blocks. My stutter before age of 16 was mostly of repetitive words type, which was fine. I could introduce myself, say my name, could talk just fine. Now it includes blocks, which is the worst type of stuttering. You literally CAN'T say what's on your mind. Fuck this shit, man. If it wasn't for this stuttering, I'd be a regular college kid, but no, I was the chosen one among my whole branch. There's literally no stutterer in my branch of 250 students, except me. Sometimes, I wish there was no me. I don't want to suicide, but if there was a button which would erase me from this world without any pain, and delete my memories from my parents', friends' mind - I'd press it.
