I admire more than I can hope to write the strength you've tried to show in dealing with this City. You remind me of my own maxim for myself (That being: You either define your problems, or your problems define you.) I respect you for that. That strength is something I can only envy.
However, I don't think something as severe as rape (no matter how it happened) can ever be simply brushed under the rug and ignored, and I don't think my little maxim can hope to cover something like that (I usually only employ it when speaking of my relationship with my father, which is rocky. Just to give a "scope" to it). I think the best thing you can hope to do is seek a therapist who can help you work through this constructively, and truly help put it behind you.
As far as your appearance goes, I don't think that's going to hinder you from meeting a good guy. A guy who won't get to know you based on a passing glance isn't a "good" guy, and doesn't deserve your time. That, at least, is how I see it. I'm not very familiar with ingrown hairs (I only shave my face, and years of shaving the pitiful peach fuzz I get on my chin for JROTC practically stunted my hair growth there), and thus I'm not familiar with the scarring they can produce, but I know for a fact that vitamin E oil can help reduce the appearance of scars.
At any rate, you are in college. You have PLENTY of time.
Keep your chin up City_of_Angels. You're a strong person with what seems to me a good head on your shoulders.
