Hi
In my first year of college I was so introverted.
Then went I got in my program which was the same group of people taking the same classes for two years I met one person who became my friend. Then from there I slowly started making friends.
When I was high school I felt like I didn't fit it. In college there's no such thing as fitting in. It was very cool. All the all 'cool' things didn't apply. Chances are you'll meet people you can relate to, who like you for you.
Good luck. Cut yourself some slack (a lot of it). Takes time to practice social skills (I'm a learned 'extrovert').
