Get your blood work done at regular intervals and confirm that fear. I've seen a lot of people show impressive bloodwork results online. But again, don't believe internet randoms, just talk to a doctor and get your blood drawn. See for yourself.
I had 193 LDL-C, which is about 97th percentile, and I'm fairly lean so I can't look to weightloss as a solution. I was scared when I saw this measurement, and after some research started a mostly plant based diet. I purchased another blood test 10 days later and my LDL-C had fallen 50 points to 143. Both tests were reliable; performed by Quest diagnostics. I hope I will continue to improve. I feel a little shitty though, perhaps I haven't mastered a balanced plant based diet yet. I do eat lean meat two meals a week. I believe a proper plant based diet takes more skill to balance than one that includes meat.
I also believe that what works for one might not work for another. So yes, trying different things and getting measurements is good advice. I'd warn against chiropractors (they call themselves "doctors", but not of medicine) on YouTube telling people that cholesterol doesn't matter; it is a risk factor, but only one of many factors.
