I'm a year younger than you with similar experiences. When I was 19 I started speech therapy at the clinic my university had after spending my teenager years not getting help. Currently doing it for the past 5 semesters, including summer terms. Before I got help I could hide it for the most part, but I was not confident, had anxiety, and unhappy with life. I tried do speech therapy again in high school but stopped b/c I would have missed class and didn't like the fact that I needed help at the time. I hide my real feelings from my everyone, suppressed how I felt. Had few friends. When i got to College I faced the hard reality that I needed help. It's okay to cry, the 1st semester I got help I wasn't feeling like i was improving and broke down outside my dorm. Over time I was able to use the strategies I learned well enough to hold a conversation and ease out of any stuttering. The hardest part was realizing that I am stuck with my stutter. Trying to break my anxiety social habits was tough, it's still tough, but you have to work hard. You will build confidence over time. 2 weeks ago at work i got a girl's # and had a block on her name. She thought I forgot her name, but I tossed a joke saying that I stuttered. I don't like to talk about my stutter but thought what the hell, why not. You can do it.
