I must express frustration

I will be the first one to say I'm not perfect and that I have some major problems. So, in my rant that shall follow I do not speak against anyone specifically nor do I say I am better than anyone.
However, I must express frustration. My mother was right and I don't like that. As I'm sure no one likes to admit their mother was right. The worst thing is, that with regards to this issue, I defended someone else, I had my mother so angry at me that she threatened to kick me out. I gave up so much in defending one person and their family that I am still bearing the anger of my family years later. And after all of that, my mother was right. And that makes me mad, cause I fought so hard, I did so much to be sure that I was right and that I was defending a good cause and now I go and find that the people I was defending hate me, are expecting me to do ridiculous things and would have no problems with something bad happening to me.
That's what you get for being nice I guess. That's what you get for loving someone and standing up for them. Well, I've learnt my lesson.
Anyways, that was my rant, now I'm going to go try and distract myself from my anger.
