Should I be worried about this week long headache?

For a week now, I've been having mild headaches. It's not UNBEARABLE, but it hurts. Its not in the back of my head I don't think? I'm really scared. Because I was reading things about aneurysms and I'm scared that's what I have! I'm only 16 and I don't want to die. I would go to the doctor but I'm going to Disney, leaving tonight for my sweet 16 celebration :( i told my mom but she hasn't said anything about it being life threatening. Maybe im worrying too much iim always stressed, but this headache itself makes me MORE stressed! I'm so scared. :( help me please.
