Bullies are mean. Obviously.
Whether it's verbal or physical, you've been or are going to be bullied because you're goth. It's like an acne cream that takes away all your acne, but may kill you in the process. A double edged blade.
My first point of advice would be to say something witty in return, if it's verbal. A rather cheesy, textbook type example:
"You're a dirty goth bleggh!"
"-some sort of witty response. Like I took a shower this morning or being goth has nothing to do with my personal hygiene.-" I don't know... I'm not exactly witty.
But if it's physical, for the love of Vulcans (get it, because Vulcans have no emotions...) tell someone as soon as possible. Punched/stoned/kicked while boarding a bus? Tell the driver. Or better yet, phone the police. Get a good look at them, call the police, they'll deal with it. If the police won't help you because you're goth, then the police in your area get their tongues stuck to icepops whenever they try to eat them.
Now, being bullied at school is a whole other story, I get bullied for multiple reasons and none of them involve my being goth. Most of them have to do with my sexuality, my support of gays, and the fact I'm vegan. But if someone really has a problem with you being goth, tell your teacher, for crying out loud. Tell the teachers, principal, anyone. As long as you aren't violating any rules at the moment (like the fact at my school, wearing hair over your eyes is a no-no for some moronic reason.), they are likely to deal with any verbal abuse. Physical abuse is something completely different. Tell the principal, and if they don't deal with it, contact the board of education and they'll deal with both the principal and the student. Really, I'm being serious. Look up the phone number for the board of education for your county/state/province/city/whatever. Tell your parents, as well. They'll help you if they already let you dress the way they do, but if you dress goth behind their backs, then don't give them a reason why they're bullying you. Simple.
The short version is stop the verbal abuse before it goes to physical, and tell anyone about any way someone has hurt you. Your parents, lover, teachers, principals, priest, doctor, whatever. If you don't tell anyone, then there will probably be no way to resolve it. If you don't tell anyone, then it'll get worse.
