Not really under any more stress than usual.. I'm always on bad terms with my grandparents (I live with them.. Mom doesn't have alot of money, dad left when I was 6 months old, blah blah blah, life story life story..).. that hasn't changed for years.. I drink Red Bull sometimes, but not all the time, and it never bothered me before anyway..
Christmas breaks? Yeah right. I'm homeschooled and perpetually behind a few days, therefore I only get Christmas Eve off when it comes to Christmas breaks. That's it.
I'm always under stress, but I'm not stressed out any more right now than I have ever been, so I really don't think that's it. And I KNOW I don't have an ulcer.
