I certainly do wish the path to freedom weren't filled with so many rocks on which we stub our toes.
This is such a challenging passage. Your physical sufferings may well be worsened by that wretched depression. This becomes such a vicious cycle: depression caused by withdrawal, then depression causing increased sensitivity to pain, then the intensified craving for relief, any kind of relief.
You mentioned that you don't react well to antidepressants, but today there is a huge armentarium of medication and a good psychiatrist ought to be able to find something that can help alleviated the psychological pain.
I agree with the post that said your *true* frienRAB will be kind and understanding. It is too hard to go through this process alone. I felt much better after I "outed" myself to my 3 closest frienRAB. However, I do understand your reluctance and fear to acknowledge your dependence.
As has already been said, keep coming back here for support. I found that even the journaling of my journey seemed to help.
I know that this, too, shall pass even though it is an extraordinary challenge to our survival.
