Human, why do you have to say "bye to her?" You could simply accept that she is, maybe, more of a friendly aquaintance than a "friend" in the sense of a close intimate. Calling her up to make a "good bye announcement" sounds pretty passive-aggressive to me. This is more about you being angry and wanting to vent your resentment at her. You know she'll likely question why you have come to this decision, and that will open the door for you to give her a good piece of your mind . . . about how she hasn't been much of a true friend. Of course, you won't put it that way. You'll more likely say, "Well, I don't want to keep bothering you when you really don't have room for me in your busy life." This is how passive-aggression plays out. On the surface, it will be all about how you don't want to be a nuisance to her, but she'll have no trouble getting the true message, which will be that you think she let you down. This is a not so subtle way of you looking to retaliate for what you perceive as her hurting you by "abandoning" you. Then, since she is a nice and generous person, she is likely to act all concerned and be a little upset that you feel the need to terminate contact. She'll express concern for you, and I think that's what you are kind of after. This will be a way to provoke her into a heightened responsiveness. It's a little sneaky, though none of this may be part of your conscious motivation. You tend to recast your resentment as "something else." Like saying how you are quick to give financial help to people, even though you are on a limited income. That very subtly suggests that you are open to being exploited. It sounds like you saying, "Look how people take from me, but I get so little in return. Even though I don't have much, people are willing to accept things from me." The message is that you have the heart of gold, but no one reciprocates.

You can't choose your feelings. They are what they are. If you feel some resentment and, even, some anger, it's okay to own that. It's healthier to own it, than to act like Mr. Milktoast who is just so innocent and modest and never wants to be bothering anyone, while, below the surface, the anger seethes. "Well, I'll just say goodbye (to the doctor and therapist and this lady.) I'll just say good bye, and go off by myself, and quietly drink away my pain. I won't keep asking someone to accept a phone call once a month or spare me an hour once in awhile. Maybe that was an imposition. No, I'll just go drink and decide maybe I don't want to be here anymore. But at least I won't be bothering anyone. This exterior meekness is very carefully constructed. It floats on top of resentful anger. It would be okay to say, "I'm mad. I'm bitterly disappointed. I feel rejected. I don't want to be patronized by anyone saying they're my friend, when they see me as a mere aquaintance."
