I was bullied at school for a variety of things. Overweight, glasses, bad hair etc. Didn't help that we were dirt poor, my DM was a single Mum and we a family tragedy when I was 13 which made me tearful all the time.
Mine was constant low level bullying. Anyway, now I am older I look like a film star compared to my teenage self! Weight off, good glasses, I've aged in to my face nicely (VERY well in comparison to the bullies) and I have even bumped in to some of the lads in our year who have chatted me up and told me that I look great (arseholes, like I am going to just forget 5 years of insults). 
In most cases I look better than the bullies for my age and have a good life - I have done very well in my career and have a great range of interests and great friends now. I wonder if the mean girls look back and think, wow, I should have been nicer especially now that I look worse than Madeup ever did and made her life hell for it
