It happens to the best of us. We often get consumed by the mess of our own lives without realizing that there is a much bigger world out there with problems we can't even imagine. This is not minimizing the pain our own troubles has caused us because nobody can tell us how to feel or how "small" or "big" the results of it are.
However, we can be reminded that while we may feel isolated in our problems, we are not the only ones having them. Often, the person you work with, the kuya guard who opens the door for you, and even the wildly successful rich girl all have problems and the best we can do is to be kind to ourselves and others because we are all surviving together.
