Hey There! I'm 21 so in a similar boat to you, age wise and can totally sympathise with you about all those social situations you were speaking about. I think for me what was most important was letting go of other peoples perceptions about me, whether they are good or bad. This was a really key thing I did that not only improved my speech significantly but also just made me feel overall way better about myself. I am naturally quite extroverted as well but my stutter held me back from a lot of situations. As hard as it may be, if you don't let it hold you back you will feel much much better about yourself. People are always going to have something to say, whether you're doing something good or doing something bad, so just do what you want to do and what makes you happy. DM me if you wanted to speak about anything further or just vent some more. Hope you have a good day!
