I've never actually used drugs...so maybe I shouldn't have said it that way. I was looking for language to express my grief. I do agree that I am in a very unhealthy state emotionally, whatever name it's called.
Neither have I, but the point is regarding your question "Is this why I need to detach, because her sensing me like this repels?" The answer is yes, she likely senses your neediness and it's not attractive. Think about why she was attracted to you in the first place, was it because you desperately needed a woman in your life and were all clingy, or was it because you were strong and independent? You need to get back in touch with the you that she was attracted to initially. Don't expect it to happen overnight, it's going to take you a while. That's why you need the time and space as much as she does.
