Okay, hon. That makes some of what I was going to say largely redundant, lol. So I'll just say this:
No one is ever entitled to treat you badly. For any reason. Whatever you may or may not have done, or think you've done. Other people's feelings are theirs to deal with, and it's not acceptable to lash out and cause someone else pain because of some misguided view that they deserve it. You don't have to take it, and you don't have to feel like it's warranted because of who you are, or are not, okay? You have as much right to be happy, to be yourself, and to forge your own path in this world as anyone else.
As far as your future, and who you're going to be... by the tone of your post you are going to be a caring, gentle, considerate, valuable human being. Someone capable of loving and being loved. Those alone are precious traits.
