nearly finished college & feel like missed so much

hi, i'm not new to the site but i've never posted before. had acne for about 10 years.
i don't really break out much anymore but have loads of agly scars and i'm r pale so
they look terrible.
i've just started 3rd year in college and i'm seriously thinking bout dropping out,
i've realised how much i've missed out on, i feel like i can't live with people in my class,
cause they'd eventually see the real me and i couldn't handle it but now i've realised
i've totally isolated myself. i have no really close friends up here.
the course i'm doing is in tv prod too so it's all bout how things look. i just don't feel i have
the confidence to make it in this job.
i just see this really long lonely year ahead, i'm so obsessed with my skin i was even in my
madness considering becoming a beauty therapist or dermatologist althou would never get
the course.
anyone else feel this way? any advice
