Protecting from false friendship Options

I'm not sure if I'm posting this in the right place, but anyway, the problem I have concerns two ex-friends of mine. I've known them for 8 years, we were best friends, but the last two years were completely unsatisfying for me. One of them always seemed unhappy with me around and she simply sucked (IMG:style_emoticons/default/evil.gif) all the energy in me. After one hour with her I was depressed (IMG:style_emoticons/default/fie.gif) and she started to shine and be happy (IMG:style_emoticons/default/harhar1.gif) . The sadder I became, the happier she was. I never felt true friendship feelings from her and I found myself disliking her a lot, but forced to maintain the relationship because of my other friend, who was convinced that the three of us were the best friends in the world. Anyway, they did some things to me that bothered the hell out of me, I explained them what was the problem...so what? They ignored and ignored...
Finally, I decided I don't want to be their friend anymore, because they just made me feeling bad, I wrote my decision in a 'friendship grimoire' we shared and they agreed. Now, one of them continues calling me, e-mailing me and tries to convince me that I am crazy and stubborn and unhappy. I am not. I really think that the decision I took was for my own personal happiness ( I even asked the tarot and I got the answer that I am going on my way now, becoming who I'm supposed to be, eliberating me from a painfull past, and so on)
I don't hate them. I just don't them around me anymore. Their opinions about me and my choices and my behaviour and my boyfriend and , yeah, even about my breasts or my intelligence were simply mean. Always making me feel stupid and even telling me that I am stupid. I don't want them anymore, not now, not after five years from now. The problem is that one of them is kind of haunting me, an
e-mail from her makes me cry, not because I miss her, but because I want her completely out of my life. I told her that, but like always, she thinks I'm in a phase. I am 22 years old, I'm not reaching puberty or any other kind of adolescent crisis, and I know that I am capable of living my own life and taking my own decisions.
The feelings I still have when talking about them (deep sadness , which I cannot explain otherwise; it covers me and as soon as I take them out of my mind I'm smiling again), the sensation of someone just trying to mess with my mind and making me think what they want me to think...I am not sure, but from what I read, it can be named psychic attack.
Well, I want to end this. But how? What I've tried until now (ignoring them, refusing to talk about them) didn't work. I am still ready to cry for hours without any other reason but that of another mail from one of them in which she continued to tell me that I am wrong and she is wright, and that we'll be together again.

gee-gee baby,
i feel you, and you know what, i kind of feel like that with somebody in my life but we're connected by blood, and i know somebody feels like that with me but we're connected by child.
i like the person who wants me out of their life, have to consider that there's some divine work that has to be completed first because leaving out of their life is ideal, there is always that unforseen element that has to be considered.
as for you, you're not connected to these people in any sort of way except by association.
obviously, they're selfish and unrealistic because they don't want you to leave their circle because they feel the strength of you and they're can't dare to face their own ugliness as the reason why you want to leave them.

you have done the right choice, and i would say keep diligent at what you are doing but have an open heart. sometimes, people do change when they face their own faults (which is rare) and you will know this for yourself when you hear the tone of their attitude.

but for now, be selfish and stay off the radar. if they send you an e-mail, erase it.
tell your mom and pops to say that you're not there when they call,
when they come over, tell them that you're going somewhere with your parents, and don't go where they frequent at.
