Prayers for my daddy

I just want to ask you all to pray for my dad. He's kind of going through a rough patch with his health right now. He’s been going to the doctor a lot lately to figure out what to do about the buildup in his carotid artery (the main artery that supplies blood to your brain.) He went to a specialist earlier this week; they have plans to do an carotid angiogram, as soon as it’s approved by his insurance. The angiogram will give the doctor a better idea of where the blockage is and how to clear it. After the angiogram, my dad will have to undergo a carotid endarterectomy to clear the blockage in his neck. He’s really nervous, but has faith it’ll be ok. In addition to this, he needs to quit smoking (he’s been a smoker for over 30 years) and cut back on his coffee drinking (he currently drinks about 8-12 cups a day.) Both of my parents work in the medical field (mom’s an intensive care nurse and dad’s a respiratory therapist), so they understand what’s going on and how serious this can be. I know they’re both very nervous, as am I. My dad’s an amazing friend, advisor, and parent. I just want him to be around as long as possible. Your prayers are greatly, greatly appreciated!
