Having Perspective and Complaining

Just recently I found out that the postal service lost 5 out of the 6 boxes of books I had sent home. Apparently, I didn't tape the boxes sufficiently so they broke. I responded to this setback by trying to give myself perspective. I told myself that this isn't a big problem in the grand scheme of things. In fact, I've been very lucky in my life overall; there are others who have certainly suffered more.

To magnify and solidify the impact of having this perspective, I looked up YouTube videos of dying people sharing their thoughts on life. I found two people dying of cancer--both were relatively young. I reacted to these videos by telling myself that I don't have a right to complain. I don't have cancer or any serious health condition. I'm not dying. I'm just a person who lost some books.

I'd say that my efforts to comfort myself have been successful, but they've sparked some worries about the effects of having perspective. On the one hand, I think it's important for people to have a good idea of how their lives are going compared to others. On the other hand, it's quite depressing to keep telling myself that someone else has cancer. I'm not sure how to have perspective while not replacing one negative emotion with another.
