It depends.
There have been times where I've found myself to be too hideous for society (I compare myself to my friends who happen to be all goddesses, and I'm just... ugh.)
But then I *really* look at myself and I'm not bad... not gorgeous or anything, but OK. I've had my share of compliments.. people telling me that I'm pretty, beautiful, cute and all the synonyms in the world. Yet, I'd also have the reverse... I remember a particular moment, I was in my final year of highschool and two friends (right in my face and infront of my other classes and homeroom teacher) one of them goes to me: you're really ugly and the other friend agrees saying: you're probably my ugliest friend - that just... that just stung me and really lowered my self esteem (not saying I had much of a self esteem to begin with), but to hear that from your own friends... A much more recent case was when my ex boyfriend said he needed to drink before he slept with me (whether he be joking or not, it still cut through me) and I had another ex before him, who left me with no explanation... to this day, I think he left me because of my looks... bleugh, they were both bastards anyway.
Now, I'm with a guy who has seen me and loves me the way I am. That ex who said he needed to drink to sleep with me... well, he's become the stalker ex, still in love with me and wanting me back! ha!
