Everyone here is going to give you more or less the same few answers, but allow me to throw an extra one in there that may be missed, and no doubt will shatter your hope and self worth..... er... no offense intended...
You may be genetically incompatible with most females.
Despite all of our glorious achievements, our skyscrapers and TeeVees and plastic fake dog shit, we're all still animals deeply hardwired to preset evolutionary conditions. Women can actually smell good mates. Not consciously of course, but on a pheromone level, females can detect certain traits that indicate if you are a good match for creating offspring.
Seriously. Females will (to some degree) show preference toward males that can produce strong, healthy babies, even if babies are not wanted nor intended, it is still a factor.
For example, you mention that you have acne. It's an indicator of poor skin caused by overactive (or under active) sebaceous glands, and its coded into your pheromones along with immune system strength, physical and mental potential.
Alright, so what the fuck was the point of all that? Don't get me wrong, I'm not trying to say you're downright fucked with the fairer sex, but if it troubles you so much and you want to change it, be prepared for n up hill battle.
To improve your chances I would add that you may want to start working out. And I don't mean hurr-hurr-meathead working out, but maybe try to starting jogging a few miles? Is there a pool at the college you can use?
Also, if you're looking around campus and basing your wants solely on looks, then you're asking for a kick in the balls. Are there any anime or comi-cons in or around your area? check those out as a way of finding someone who shares your interests. Speaking form experience, a woman that can be your lover and friend with the same interests will go a long way towards a healthy relationship.
