If you hold your breath, your blood pressure will go up. So it is important to breath normally.

I would go back in for additional blood tests. Also, you can still get good fats and cut out bad fats. You can do this by eating avacados, olives, olive oil, and nuts (and nut spreads.) So, if you work daily to cut out some of your meat fats and add more vegetable fats you may be able to lower your cholesterol.
