Treat the year at Lincoln as a foundation, then have a great summer working, travelling, reading, or whatever, and start with a clean slate at the new place. Throw yourself into social life (if you are a social person). Join clubs and what not. You may find that some of what you learned at Lincoln will help a bit when you re-do some of the same stuff next year.
At this stage of your life, time isn't really wasted, as all experience is formative. You took a detour, and are now back on the main route.
