I know the feeling believe me. The key is to keep pushing yourself wether you embarrass yourself or not. I made the mistake of going through periods where I didn't care got things done and made progress in fluency due to becoming more confident/comfortable putting myself out there. Then I would fall into a depression, isolate myself & get worse again, this cycle has went on all my life. You have to ride the momentum so to speak. You said u were successful, so take advantage of that little bit of confidence & train yourself to keep taking action no matter what. Eventually I bet you'll start stuttering alot less in social situations when you become more comfortable doing it. Stay motivated bro!
