To follow the song, I'm heartbroken that I will never be able to have the relationship I want with her, when she doesn't call me (i.e. "leaves"), I feel frantic with guilt and abandoned, when I try to forget her for awhile, she occupies a spot in my mind so powerful that everything else just fades and I can't stop focusing on it and I start to feel physically ill.
There's never been abuse, drinking or drugs involved. It's all passive-aggressive mind stuff that has gone on for years and years. I'm like her mental prisoner and she has no idea of it. She wants me to be a cookie-cutter child and if I dare to be different, everything derails.
Do you have any experiences to share? My therapist suggested that I attend a group that meets to discuss co-dependency issues.

I don't have anything significant to add except for virtual support.
