Sorry I can't help you on most of your questions. I will however point out that when you get up to go to the restroom, lets say at night when in bed, make sure you sit up, wait a few seconds, maybe about 10 seconds. Then get up. Or if you stood still for a good moment either be sitting down reading or just standing; remember to stretch and to also drink plenty of fluids.You need to ease your mind also. Especially when you have a lot of things to in your head. The honest truth is that worrying does not solve the problem and may in fact create more for you. It's not healthy mentally or physically,so give yourself personal time, and also family time.Do subtle changes in your life, like exercising. If you are then keep on. Park your car as far as you can from stores you visit and your house, all the extra walking should get you a better heart rate
. Obviously eat healthy and always take the stairs instead of elevators (if possible).
