Concerning the cholesterol...
As controversial as it seems, the best thing for high cholesterol? Polyunsaturated and Monounsaturated or also known as Essential Fatty Acids (EFA's). The best source is olive oil, fish, avocado, nuts etc. They raise HDL while lowering LDL/Triglycerides.
The absolute worst thing for high cholesterol is trans and saturated fatty acids (I personally call these Deadly Fatty Acids). They raise LDL/Triglycerides while pushing HDL down. Those two are the ONLY fats you should cut. NOT unsaturated fats.
As an aside, dietary "cholesterol" actually doesn't have anything to do with your cholesterol, so don't worry about that. It's OK and even much better to have your eggs with their vitamin-rich yokes. They are worth their marginal amount of saturated fat (and that's natural saturated fat so it's not as bad as the artificial ones in junk processed/GMO 'food').
Unfortunately, your own body fat does have a lot to do with your cholesterol. Your cholesterol level will also actually spike when you are in ketosis (true fat loss) because of this fact. I've seen my own labs reflect this. It has to get worse before it will get better. Don't get discouraged if that happens.
Here's my records of cholesterol, for whatever they may help you or anyone else (can't find them pre-2011 sorry. Not paying $80 for records lol)...

^that's not so shabby, considering. Not great but not horrendous either.
To clarify, the 'Mediterranean diet' caused my most severe hypoglycemia attack to date because I'm apparently among the 3 out of 5 that experience horrendous blood sugar spikes (worse than after a candy bar) from so-called 'whole wheat'. That was the significant change I'd made, replacing all the white flour carbohydrate sources to 'wheat'. For me, that was a nearly fatal mistake but not likely to be if you're the 2 out of 5 that don't get wild sugar swings from 'wheat'. It is, clearly, a very good plan for cholesterol and heart health and also weight loss. But, beware of 'wheat'. Its not the same wheat past generations enjoyed. Its 'genetically modified' garbage and good luck finding any of it that isn't. I also have metabolic issues to begin with so that likely has to do with it. Not necessarily typical.
Another clarification concerning the higher cholesterol from ketosis, I have been in ketosis the entire time I've been on T to date (I can actually see this in... my urine; I have a oily kind of sheen that's because of the ketones; this is not the same as diabetic ketoacidosis though). I've been watching what I eat (not technically a 'diet') and my cholesterol is borderline. I feel it is like that now because of my body using its own fat for fuel. Even though my weight hasn't changed that much, I've displaced the fat while gaining the muscle... same difference as 'fat loss' really.
Just in case you or someone else might find all of that helpful.
As to the blood pressure... might be time for meds. Beta blockers are wonderful. I was on them briefly because when my cortisol was high (117 mcg/24hr), that was causing it to crest into the 140/100 range, averaging 130/90. Those brought it right down to 180/80-ish.
