Lessons in Self-defence

EMOTIONAL DISCLAIMER: I was pissed AT JUST ONE PERSON when I wrote this.

Why is it that when a friend says "I look disgusting today" do we all feel the need to coo soft words of comfort and confidence to make her feel better?
Or when a friend says "I did shit on a test" we all need to say 'Aw, nah honey! You probably did fine!"
Has our soceity become so delicate and sensitive that we can't say "You do look like shit" or "Well, you do suck at persuasive arguments"? In other words, have we become too sensitive to tell the truth? I've started to notice other people defend me from myself. If I say I look shit, I look shit. I'm not bothered by it; I'm merely making an observation. When I say "No, he wouldn't like me" it literally means "No, he wouldn't like me". But instead, people seem to think I'm seeking words of support and validation. I get treated like those chicks that are like "Oh I'm so ugly" because they want their friends to say "OMG NO YOU'RE NOT".
I don't need people to defend me from myself. I don't need kind words to make me 'feel better'.
With that said, I seriously do appreciate and admire the valiant efforts of friends to save me from myself. Maybe I am too harsh on myself. But others seem to be more hurt by opinion on myself than I am. Maybe they don't realise that I'm not seeking comfort, just an open ear to listen to me, and accept what I have to say. I always feel like an ungrateful bitch when I think these things, and explain my arguments. Because I don't need sympathy, because I'm fine.
Maybe I'm seen as a no-confidence, low-self-esteem teenager, just because I accept the truth about myself. Because, when I look shit in a photo, I say so; because I don't make excuses for doing a dodgy performance, or getting a crap mark.
It bothers me because I feel people are just lying to me, treating me like a delicate flower, and clinging to the tiniest of chances, just because they, somehow, think I can't handle the truth. I find that insulting in numerous ways. I feel insulted it when people say insincere things; I feel insulted when I'm percieved as something fragile, breakable, a 'damsel in distress'; and I'd be especially insulted if people didn't think I have enough sense-of-self and balls to accept the truth.
Me: 'Lols man I look crap there'
Person 1: 'Stop saying that. You're beautiful'
WHILE THAT'S LOVELY AND EVERYTHING, I can see what I look like. Don't patronise me.
So since I've thoroughly convinced you I'm an asshole, I can now tell you about the walking hypocrisy that is myself (Ah, did I almost trick my no-readers into saying 'aw no. you're not an asshole' even though this argument supports the fact I plainly am?)
When my friends are upset over things, I'm always willing to be a confidence booster. While people mercilessly slander themselves, I'm always willing to stop them. But when people are insincerely insulting themselves for scraps of sympathy and assurance, aside from the fact that's a confidence problem in itself, I'm rarely tempted to say anything.
I think it all comes back down to truth. If people are saying untrue things about themselves, then that's where I step in to right the wrongs; to truth the untruths.
