I am so sorry to hear about what happened. It was not considerate nor helpful. It is important to surround ourselves with those that are supportive, and unfortunately, the reality is that not everyone will be. However there are many out there that will hold the same values that you do, it is a matter of finding them and cherishing those that treat us with the same respect, consideration, and courtesy as we would treat them. Find those beloved family, friends, and coworkers to be your support network instead.

There will always be some element of selfishness towards self preservation. However, I found myself the other day thinking something similar though as you have expressed in noticing a trend in various generations, not just adults and yet not everyone either , in seeing signs of being and more self absorbed and self obsessed, and less compassionate, considerate, and courteous as a result, such as: various media outlets tend to support this, Twitter, Facebook, etc; we even have a term now for photos that are so very popular and very consuming... the "selfie"; and could go on.

Know that you are not alone in seeing this in some others but know too it is not everyone that can be categorized this way. It is frustrating but it can make a difference in recognizing how NOT to conduct ourselves and to rise above it when it does happen by continuing to think of others, not just ourselves, help those that have been slighted, and "be[ing] the change you wish to see in this world."-M. Gandhi.
