These things do happen, especially when we live in a world of stress. The best thing you can do to support him is to first calm yourself down, and to bring forth a spirit of peace rather than of worry or fear. Your fear in this moment will not help him, it will only burden him. I understand how scary it is to face the thought of losing the ones we love. I've been in your shoes, when I found out she was diagnosed with cancer my heart fell, but life went on.
This event helped me to realize how precious life is, and how we tend to take so much for granted when actually every day is a gift.
No amount of fret or worry will make things any better. In fact, it will only make it worse. Again, the absolute best thing you can do is to provide your support in the form of emotional stability. Gather your strength, stay optimistic, and work steadily to help him improve his health, no matter how things go.
There are plenty of excellent, non-habit forming medications for lowering cholesterol and blood pressure. However, diet, exercise, and balance will work miracles.
If he is having a hard time with something emotional, then perhaps you can suggest that he see a therapist in order to talk his worries out to someone.
Stress is the cause of most disease, so you must work together to bring balance and wellbeing into your lives. If you make this your priority, you will succeed.
Btw, you may consider taking up some activities that help you to decompress. Yoga and meditation work miracles for these sort of conditions.
I wish you both the best.
Sincerely,
Daniel
