All I would advise is don't push yourself too hard! The first months of uni held some of my best memories. Try not to focus on your stutter, focus on finding clubs to join and to meet some people, but don't overwhelm yourself! You'll have plenty of time over the next month to meet people, I only met one of my best friends until a few weeks after joining. You might find that some people you meet might be temporary friends, this is normal for everyone. I actually remember not stuttering a lot during my first weeks I think because my brain was so distracted on starting the course or meeting people
