Hi Khaz
I work as a lecturer at college, and it is something that we do not tolerate at all. It is also much easier to withdraw students at college if they are in any way misbehaving or causing trouble. Your personal tutors will be really supportive and you certainly wont be the only big person at college.
By September, you will be even slimmer, have more confidence, and be ready to take on the world.
Very best of luck with your course and your diet journey.
