Thank you for reporting on your experiences. It's good to be honest with ourselves about these kinds of important things. And if possible, to be honest with others about them, too! Sharing what you did and how it affected you may help others, so good for you.
Your diet sounds very healthy! It sounds a bit like the "Mediterranean diet" some people adhere to. It's also similar to mine - I am vegan but also eat free range eggs and shrimp. No wheat. Lots of produce, rice, and organic grains like quinoa, oats, corn.
Regarding your symptoms - shortness of breath, intolerance to exercise (tired easily), etc. This could certainly be related to the injections you took, considering they are known side effects, and because they seemed to begin after you got the shots.
If you think that's the case, there are methods of removing toxins (like the spike proteins from the Moderna and Pfizer shots). A really good one, backed up by tons of excellent research, is found at the FLCCC website. They have a specific protocol for detoxifying from spike protein exposure, something I have been trying out because of my arrythmia (fast and irregular heartbeat). I also get shortness of breath and some other symptoms, probably due to shedding from a vaxxinated person at some point. This protocol is specifically for people who took the shots. Two of the main actions you can take are Ivermectin, and intermittent fasting. Ivermectin bonds to spike proteins and helps your body remove them. It also reduces inflammation, and is a powerful antioxidant. Fasting (starting at 12 hours per night, 3 days a week, and working upward from there) is an excellent way to clean your body of toxins, because once it uses up the food in your stomach, it begins to look for other material to burn for energy. This includes toxins like the spike proteins, and anything else that shouldn't be in there. Fasting and ivermectin work very well together (synergistically). There are other things you can try, but those are probably the ones you should try first, if you can. Read the link for more information and details.
I'd be interested to hear how things go for you, even if you don't try these methods. Let's stay in touch. :)) Be well.
