I am 19 myself and haven't had anyone really care about me, I've had one...kind of boyfriend...haha. At the age we are at, I think seeing as we are all still so green and just trying to survive, it makes relationships fickle and a little shallow. So it's completely not unusual and almost to be expected that relationships we have had or might have aren't as great as they will be later (of course, there are exceptions).
That doesn't make it suck any less of course, all my real bad depressive moods are triggered by lonliness, or looking at my best friend and realising how gorgeous she is and I am not. And we are surrounded by depictions of perfect relationships in media all the time, making us believe that's how they all should be all the time.
And the nose job? Don't be silly! You are gorgeous, and even if you think your nose is big - remember David Duchovny is sexy as...and er, some great broadway actress? Was told she would never be famous unless she got a nose job, she didn't get the surgery and...I have a feeling it was Barbara Streisand...it was in a Glee episode...haha, sorry. But you get my point, don't see it as an imperfection because it isn't. It's just a feature, part of what makes you beautiful. And remember, the parts you usually hate most about yourself is what everyone else seems to love
