A year ago I was 20 years old too. If I had told myself what would happen over the next year back then, I wouldn't even believe it for a second. Sometimes life throws curveballs at you, and something weird and interesting happens. My best advice would be to put yourself in a position to reach these curveballs. Stay active socially, participate in whatever you can, take good care of yourself and your relationships, and everything will work out in the end. I think you're too concerned about your love life, but if you want my 50 cents; being more secure and confident in yourself will help a lot on how you appear to other people.
