You should be stronger, girl. They do not deserve to make you sad. I am also in the same situations and the worst is I experience it with family members too. They even blamed it on me, and told me it all my head, stayed away from me etc. However, why you should care? If they could say what a pity then you can mock them too.
About human aspects then you were right. But you are not relative to them. Human are not the same. There are some are superior comparing to each.
