How can I shake this feeling, please help?

i have had all these worries recently because i have started college at a bad school near home because it was a full scholarship. i gave up my dream school. now i want to transfer to that dream school after just the first semester. my problem is that i feel somehow tainted just by having this experience at a school that is really trashy. it's like i'll forever look back on it badly and i'm embarred to tell people about it. i'm just really bent on success and living in that kind of environment. is this anxiety/ocd? or waht? please help with what you think.
