there will always be people who will hurt you. they may be an acquaintance, a random stranger, or worse a friend (or "friend") or even family. there will be others who will go out of their way to ostracize and intentionally hurt you. there are no exemptions, no prerequisites, no conditions. there are people who, just to make themselves feel better or who feel they have the right to hurt people just because they think their meanness justifies their reason, will actually make it a point to make you feel "unwanted" and will go to great lengths to treat you like an outcast. i know. i felt that. i have been treated that way by people who i considered to be my friends.
bottomline is you just have to learn to let go. let go of people who do not see your value and move on with your life with the people who do. the saying that when a door closes, a window will open or better yet, another door will, is true. there will be people who will be worth your while. worth the friendship and worth the trust. you just have to learn to see, choose and accept who they are. life will not be fair every time. we all have to learn to adapt. you can only take so much crap in your life. there will come a point wherein you have to weigh things out. you will have to see if all this and all that is worth it or not. on the other hand, look at it as life giving you the chance to sift through the people in your life. once the sifting is done, you may have been left with only a handful of people, but for sure they are the best of the lot.
in the end, you will know who are worth keeping. thank God there are people who stay true and still believe in you and whose definition of friendship and family is the same as yours.
