Firstly i must say that your hair is BEAUTIFUL, i left you a few comments in your fotki. The breakage is not all that bad but like i s aid in one of the comments that you needn't beat up yourself too much about it. Trust me i'm the Diva of breakage and i know it can cause setbacks and mess up ones' goal but hey the rest of your hair is still very healthy, it just the ends that needs a lil triming (not much) and you should have your hair like spanky new again.
HHG to you and continue to TLC you hair. Ease off those rubber bands too ehh!
