Frustration

I know that I have hurt a lot of people in a lot of different ways. I hate how I have pushed away the people that I care about the most with my selfish feelings of anger. But I am changing my attitudes and trying to get better, because I cannot stand to lose another person that I love ever again. I am bettering myself and learning how to love people the right way.
With all of her negativity, I feel like she is just holding me back from getting over things. Yes, she is a great friend sometimes, and I am thankful for that. But when she gets mean and bitchy and malicious, I feel myself getting angry and mean right along with her, and I don't want to feel like that anymore. It is not okay to be malicious. It is not okay to hurt the people that you love on purpose, no matter how much you are hurting or how angry you are at them.
She is there for me when I need to talk, and I know that she cares about me, but until she stops with the maliciousness and the vindictiveness, I can't have her in my life. I am sorry, but there are more important things in life than being angry. I hope that you realize that soon before it destroys you.
