Oh, if true, your story is so sad.

Glad you got adequate medical care.

I think the attack happened because you have come to substantially dislike your stay in China over the months: It creates a constant stress. You will be OK as soon as you arrive back home in the UK.

Please watch your food. Sausages and other processed meats like bacon are not healthy. You need plenty of fresh fruit and veggies (boiled veggies are ideal). Eggs are OK. Chicken without the skin is OK. Avoid added sugar.

There are foods (mostly anti-oxidants) that - over time - help cleanse the blood vessels and decrease the plaque, like turmeric, garlic, apple cider vinegar, coconut oil. Exercising is also essential.

Wishing you a safe trip back home.
