Discussion: Books You Shy Away From

I'm gonna be completely honest with you guys and admit that there are certain types of books that I will probably never pick up. And it's not because I dislike the genre, but it usually has more to do with the topic these books discuss.
You see, in my line of work (for those who don't know it, I'm about to be a doctor) there's a lot of good things happening. I mean, babies get born, people are cured or we're able to help them in some way that makes their life better.
The other side is much less pleasant and a day at the hospital can consist of me telling a patient that he or she has cancer and there's nothing we can do about it. Or actually helping someone be as comfortable as possible in their last few hours/days.

I wouldn't trade what I do for anything in the world, but I have noticed that since starting my internships, I have started to avoid certain topics. When I'm at home, reading, I just want to relax and get lost in the story and not be confronted with how harsh reality can be sometimes. And maybe this will change in the future, but right now I need magic, romance and nothing that comes too close to that reality that I see in the hospital every day.

So while I know that there are some amazingly beautiful books out there dealing with cancer, death, suicide, war, drug abuse, eating disorders, physical/emotional/sexual abuse, I will probably not read them anytime soon. These are the topics I shy away from. For example, I know that everyone and their great aunt is raving about John Green's The Fault in Our Stars but after I read the summary I couldn't bring myself to jump on the bandwagon.
I used to love books dealing with these types of stuff and I used to read SO many of them. But right now, everything in me flinches away from it.

Also, I cannot bring myself to read anything that has to do with World War II. I am not even entirely sure why, but it might have to do with the fact that my grandmother lived through this war and it just hits a little too close to home. Because Germany is right next door (seriously, I live about 20 minutes from the border) and it all happened here as well.

I also know that it's crazy that I don't read contemporary or historical novels dealing with war, because hello, in those fantasy novels I love so much they're at war a LOT. I know this, but when it's swords their fighting with it doesn't seem so real. This is also why historical fiction dealing with war where they still fought on horseback with swords works.

So what about you? Are there topics you can't bring yourself to read about? Books you would recommend that would convince me I need to abandon this fear?
