harper, I hear you. I had a traumatic break up from an inappropriate relationship and I really was coping on my own. It does help to have a shoulder to cry on, but its not essential and the pain will diminish over time.
Is there anything you can do to either take your mind off the pain, or at least get your body good and tired. I promise that it will help although it doesn't seem so at the time.
SR will always be here for support and there are people who understand exactly want you're going through. It might help to read some thread by people who have broken with their As and are now so much happier.
