I feel you. I'm 22 and graduating uni next month and i can definitely say it was a hard journey. My stutter is really really bad and i have 0 confidence. I'm worried about getting a job and living a life like this. Didn't ask a question in class in all 4 years :3. Was afraid to go to the cafeteria etc and Haven't been in a relationship or even close to it in my life :3. Ik i should've made a motivational comment and not a depressing one but i just wanted to rant a bit and let u know that you're not alone. I really hope your life gets better, and your company and teachers in uni are great. Good luck. :)
