Waddup follow MacGuire student haha. To me it seems like you actually have had some pretty significant improvement in your life. You actually talk to people and consider them friends, its a lot better than before as far as i can tell. Its not like people are gonna become your best friend after a summer. If you are lacking in social skills then you just gotta practice. Stuttering leaves some pretty deep social scars, you cant expect to make best friends this fast. Dont compare yourself to others, but to yourself 1-2 years ago.
