I'm tired of thinking about college

I'm tired of thinking about college I have no problem with stuttering in my life at all. I live happily and comfortably during my vacations. My stuttering is moderate I can speak randomly and fluently unless you force me to pronounce some letters and numbers. Then I stutter. The problem is that I am satisfied and can live forever with stuttering. However, college is a completely different life. I cannot ignore thinking about it for a single day. I think about the presentation and participation during class from the first day of the semester. I waste a lot of my time thinking about stuttering. I hope to pass the university stage safely and then I can live my life with love and peace.
