I think that you are denying to yourself just how much bullying is affecting you. You should never have to 'get used' to bullying. Never. Your friend says it is a big deal because it is and she cares about you.
Bullying can destroy your self-esteem and leave you scared and frightened, with heavily destorted images of yourself. You think that you are useless and therefore deserve to be bullied, you lose focus with your schoolwork and begin wondering what the point in everything is. The bully gets away with bullying and becomes stronger, hurting you even more. Bullying carries on haunting you long after it has stopped, it chips away at you when you get older. It forever holds you back as you just hear the bully and stop trying for things, losing ambition. You can turn things on yourself and hate yourself as you cannot channel your anger anywhere else.
Just because the bullying may not manifest itself in physical forms does not make it nothing. Sometimes the marks that aren't seen hurt the most. Please talk to someone about the bullying, you deserve better.
I do like what Klutzerella said though. As long as you stay strong you can get through it, but stand up for yourself.
