Take a deep breath and relax.
You don't mention how your blood sugars and blood pressure look. If your blood pressure is normal, it's very unlikely that you're going to have a stroke and you'd be in far more iminent danger from ucontrolled blood sugars than from a slightly elevated cholesterol. Low carbing helps with all of these by controlling insulin production and lowering insulin resistance.
If you haven't read it already, I'd suggest that you get a copy of Dr. Bernstein's Diabetes Solution; it's low carb specifically for diabetics.
It's not the protein and fat that put a strain on your cardiovascular system, it's the constant over-production of insulin and high blood sugars that does which cutting the carbs controls.
They're still coming from a high carb/low fat mindset (most dieticians are).
The best way to prevent being "scared into submission" is to educate yourself. Read Dr. Bernstein's book and you might also want to read The Schwarzbein Principle and Protein Power as well; they all do a very good job of explaining why this WOE is so beneficial for diabetics.
