I Love Someone With Diabetes

My question is how you guys deal with lows at night? I just get so paranoid but my partner acts relaxed. The reason I am now paranoid though is because they expressed their fears of what can happen at night if they are to go low while sleeping. They usually wake up when they are low but it takes one mistake.
it scares me because it's a lot to learn in this. I won't lie I'm a paranoid person time and the more I learn the more I also hear what can happen. I don't think people understand how serious and scary type 1 can be. It is a lifestyle and it really does effect a lot of peoole around you. So I hope others that have nothing good to say about diabetes really look into it. Any who that was my rant/question.
