can i disable the xp buff?

[triadne]

i have this buff "road to 70"
my quests are level 14 and i am level 22.
I feel no challenge from the quests and when I level up, I feel nothing because it's happening so often.
I am gaining new skills at a rate that has me struggling to learn how to play and I'm feeling overwhelmed.
I just want chance to breathe.

edit:
okay never mind. see, i quickly deleted and remade my character because of a total messed up quest and all that. didn't see the double xp message.
so the wonderful news is, i have to start yet another character.
this is just going swimmingly!

edit:
please, someone tell me i can get rid of this... i really don't want to start again
