That's what happened to me years ago when I started university. I started to miss lectures, avoid social contact etc. Eventually I surrendered and left university and started telematic studies in other university. It is not something that I'm proud of, but it was too much for me. I will always be angry about the fact that I couldn't finish my studies there because I entered to a public major that was very demanded and required very high qualifications, which I got, but I didn't manage to have a normal life so after 3 years I abandoned, cause I was reaching depression. ​ Now I am happy with distant studies, but that was the first time that stuttering really avoided me to accomplish something I wanted.
