Back again, Curly. I see you haven't been yet, but maybe you will soon. Or perhaps you're still reading. I've been thinking about you on and off all day. And it occurs to me that, maybe, it's not just the "mean" words that alienated your DD. Perhaps she couldn't deal with the issues you were going through or, sorry to say, the fact that you needed medication. Some AC have trouble seeing their parents this way. The fact that you were close for so long may have made it even harder b/c you may have suddenly seemed like a different person to her. I hope it doesn't hurt to hear this. I'm no therapist, I'm just guessing at why even your apologies haven't quite brought her back. She may need more time to adjust to how things have changed.
Regardless, I appreciate the fact that you stopped emailing her in July. You still sent her postcards, though, and that is probably why she moved and didn't give you her address. I know it hurts, but to me that is a clear message that she wanted the constant contact to stop for now. Greetings on her birthday and holidays (the ones where people send cards only) are probably ok. But fortunately, you've already realized you should not do more than that for now. As another poster said, please let her wonder why she hasn't heard from you/let her miss you a little (I'm sure she will). It's hard to wait, but, in time, I'm sure she'll reach out to you again.
