Like "In your case, you might just need a get a way spot. Lots of people in your house. Take a walk. Don't get mad and storm out. That will add to the tension. Walking is great for diabetis. Tell your parents how the "crowd" is affecting you and that stress isn't good for your diabetes and that sometimes you just need to walk it off. Btw, cudos for your brother standing by his girlfriend and your parents being there for them. Assure your parents you aren't angry you just need to walk. Take your cell phone or iPod (but be very aware of your surroundings) if you have two ear buds in."
