college is much friendlier environment to go into, most people are in the same boat as you and the lecturers know it. plus they will all be with the same age group as you and most likely have a fair bit in common if youre on the same course so chill and enjoy it
I started last monday and wasnt really too nervous, only 11 people in my class and I have already made a few good mates which I meet at the bus interchange every morning and go for my dinner with them etc.
