I know it's hard to believe but you'll grow out those signature bangs one day and be happier for it. You'll lose the many inches of hair down your back too and this will be a catalyst for you. 
Embracing your shortness is also really smart because you don't gain inches in height just because you let go of that curtain of hair.
All the things you feel innately are okay, normal, and much more common than believed. I know it was hard trying your best to blend in but you'll figure out that being seen is one of the best ways to relieve yourself of silent suffering and to connect more fully with others. 
Sarcasm is a skill you learned early and perfected quickly. This will prove to be your armour, olive branch, and your signature - no, really.
