FlippedRHalo....it is a really good sign that you realize that your symptoms are mostly fears of abandonment. Good insight.
You might want to read the book "The Sabre-toothed Tiger". It addresses fears of abandonment (it was written for abused women--but it can apply to addictive relationships, also).
It is very easy to read and is not too big. (I know you are busy studying..LOL!
It does make a big point that the treatment for fears of abandonment do not come from a relationship with a partner (even a good relationship). Therapy and coming to grips with the source of the fears and self love.....
Stay strong in your convictions.
