You could be describing my best friend of the past 25 years. She lives a couple hours away from me and the last few years our relationship has definitely gone downhill. For weeks or months at a time she won't return phone calls or emails, then suddenly she'll start up again. What most people don't know is that she's battling severe depression and other emotional issues which has gone as far as her needing to be hospitalized on several occasions. Despite being her best friend even I know very little about her situation and never even know she's been in the hospital until sometimes weeks after she's gotten out. I have begged and pleaded for her to talk to me and have let her know numerous times I'm here for her, but she chooses to go through those desperate times alone. I have even gone as far as telling her if our lives had just reached the point where we had grown apart from each other that I was O.K. with that and we could go our separate ways with no hard feelings, but she went off the deep end! I didn't understand why she would never talk to her best friend and yet still socialized with others. She finally explained to me (and her daughter did as well) that she shuts out those closest to her because it's easier to hide what she's going through from her more casual friends than it is from those who know her best. I've finally learned to accept that our friendship is never going to be a conventional one and that she isn't always going to be there for me when I want her to because of her condition. She will still always be my best friend, but I have had to get other good friends to fill the gap and it's working well. It's not easy, and I miss my friend dearly, but I have learned to savor the moments we do have together and be satisfied with that.
