I do not have first hand experience with your situation, so I speak as an observer of what I have seen others do.
You do not really say what kind of nursing you have tried to re-enter in to. I think this can be a situation that might matter. Some employers
will not be inclined to trust a nurse with a CD history with any med administration, others will. If you have not tried for situations where med administration is not an issue, do so. That might include an Ask a nurse type job, insurance nursing (case management or others), may be some types of home health, some public health jobs etc. I know that this might be hard if hospital nursing is in your blood, but realize that you are doing some rebuilding. It would strictly gall me to go in to a role like nurse aide or pt aide, but that might be a way to prove to an employer that you will be a loyal and dependable employee, and it is an option. I cannot say to you that I would do this,but it is an option. If you were receiving services from your state board of nursing asssistance program, I would ask them if they would assist me in contacting a nurse who has successfully re-integrated in the professional world. I would hope that they have some recovered nurses who are a success story and would be willing to mentor others in this area. I read in a professional journal that nurses who are rebuilding in this area can feel very isolated and so a mentor just seems like a really good idea. Alternatively, have you met other nurses at AA or other 12 step support groups that could mentor you.
I wish you the very best of luck and encourage you to be strong. I know nurses going through our state board assistance program MUST be straight forward about their recovering status with employers and so it almost seems as if you are forced to ruin your own employment chances but I think that you can be your own advocate if you can be ready to discuss the very question at hand; "Why you should offer me this job." You might see if you can get your DAC to write you a letter saying that you've been released from treatment. You might return to her one more time to role play a job interview
OR do that with a mentoring recovered nurse. Be ready to straightforwardly recount the strides you've made in recovery that have made you accountable and responsible.
Good luck. Success follows persistence and hard work.
