Is it high BP? (hypertension). You've had a bad run of luck haven't you?
Try to take some time out for yourself each day if possible. Try meditation or pilates (stretches), going for walks & staying off of caffeine to help your BP. Write stuff down if it's bothering you, so you can reflect on it and it gets problems out of your system. Talk to someone close to you if you're feeling stressed.
My prayer for you:
Our gracious Father, please look upon your servant Levi, and help the medicine given to him to heal him. Help him to cope with stress better so that his BP will return to normal. Amen.
Hope you feel better soon & the medicine helps!
