I can relate to this problem. I had pregnancy hypertension and it was a wake up call. They made it clear that I'd likely always battle hypertension in my life time and sure enough. . . I have familial hypertension. Your family history would indicate that you are as well. This makes things like your age and lifestyle important but less so. You are likely genetically predestined for a bit more work on this end at your age than others. I would say that a second opinion with an actual doctor that can examine you would be important. What you are indicating is that medications tried are not giving you the range of blood pressure that is best? You are falling into the more borderline area (as I naturally did at an earlier age too). You seem to be of proper weight and you are exercising. I'd perhaps exercise a bit more (clear with doctor). If your steps are just that of your daily life (which does count but isn't always true cardio where you are exercising your heart). It does look like perhaps some of your dietary choices could change such as maybe less red meat? The DASH diet is proven to be helpful for hypertension. Mediterranean diet is similar to DASH. Maybe instead of three square meals, eat 5 smaller meals? But overall, I know it is concerning to have blood pressure issues and at a young age. It legitimately makes us worried about the future. But as you know, since you take medication for anxiety, worry in itself can have a negative impact. You are doing all that you can and care about your health. So, take peace in that. I think a second opinion in your locale makes sense if you are not satisfied with answers your current doctor is giving "too young" as a way to blow off your concerns.
You're pretty young and therefore lifestyle changes can make a big difference for you. Your blood pressure isn't actually all that high, so it should be able to be controlled through lifestyle changes -- not saying it will be, but it could be. We're not medical experts here, so we can't really give you medication advice, so if you think beta blockers would be better for you your docs are the ones to discuss this with. But again, you say you have high cholesterol, but you also say you don't eat a lot of veggies and do eat a lot of meat. So there's something you can change right away by eating more fish, which is high in omega 3 fatty acids which can lower your bad cholesterol. You don't say how you're cooking this food or if you're eating out a lot, but if you're frying a lot in poor quality oils, that's also something you can fix quickly. Counting steps at your age seems odd to me, as you are able to exercise much more vigorously, and we know that while walking is helpful more vigorous cardio is much better at building the heart muscle and opening the blood vessels as long as you start slowly and build up to a safe level, with your doctor's permission. Walking is for us old folks. It's also not clear at all in any particular case that stress causes these kinds of problems -- can happen, can also not happen. Depends on the person and genetics and lots of other things. Stress is also a very individual thing, as it's something we often create with our thinking but which isn't an objective reality. Life is always hard, but different people experience it very differently, and what stresses one person out is the cat's meow for someone else. If what you're doing is causing you undue stress, it's possible it's not your thing. It's also possible you have some level of an anxiety problem, and relaxation exercised and practices can help with this. There are also natural remedies that can work for borderline problems that might not be useful at all for severe problems. Drugs aren't always the thing that works best for a particular person. All this is just food for thought, as again, nobody on here is a medical expert, but just giving you some alternatives since you are unsatisfied with what's happening now. Peace.
