I don't know what to say except for that I'm feeling so depressed and hopeless. I don't see myself ever being happy again. When we had no contact, I wasn't okay but I could cope. And now that he's contacting me (and I secretly like it) I feel myself living for him again. And when he's not there, I'm not okay. Nothing seems to help. I don't want to live like this forever. People keep telling me it will get better and people are getting sick of me talking about it. But HOW does is get better? I have no hope left. I don't want to die, but I also don't want to live. I don't know how to get myself back from him. He has me all. My psychologist gives me some clarity for an hour or so, but I still find myself craving him like a drug addict (while he's with other girls). I don't know how to go on.
It sounds like the fact that you broke n/c is what is causing your pain... .is this correct?
And that your pain arises from the fact that you want a r/s with him but his actions show that he does not want the same ("he's with other girls"?
The "drug addict" analogy is actually a research-based analogy - getting over a r/s is much like drug withdrawal. This explains why you were "coping" during n/c but are now spiraling downward - it's because you took a "hit."
If this analogy is correct, you need to consider yourself to be a heroin addict, and consider: can any "addict" truly break free of their addiction if they decide to occasionally dabble in their drug of choice? You already know the answer to this.
The truth is that when you went n/c you began experiencing the stages of grief, which are very VERY painful in the beginning (especially, it seems, when you are recovering from a BPD r/s) but very necessary. As you progress through the stages things DO get better over time. For me personally it's been almost 6 months post b/u and almost 4 months n/c, and I am doing much, much better. Not perfect; not completely healed; but much better. However, you've now set yourself back by re-establishing contact. If you want to regain your happiness you need to consider what will make you happy and then DO it.
But this is the rub: you can't control his behavior. You can't MAKE him healthy, you can't MAKE him love you, you can't MAKE him stop seeing other girls. If you love him and want this from him, it's time to get honest with yourself about your chances of getting this from him. If it is not possible to have the r/s that would make YOU happy with him, it's time to go n/c again.
