License Reinstatement After Revoke Is There Hope?

Hello, my name is Robi and I am new to this site and I'm not even sure if I deserve to be here, but I have a question that I hope someone can help me with. I was a licensed Practical Nurse in the state of Tennessee until 2004 when my license was revoked to due a prescription drug addiction. Due to the shame I felt and still feel to this day, I never tried fighting for my license at the time, but long to be able to practise again and have been sober for 5 years and working in an office outside of the medical field. I just don't know where to begin. I have researched the tennesse state board of health for answers, but it seems so complicated, I just don't know what step to take first and after all this time, I don't even know if I have a chance at getting my license reinstated. I guess what I'm trying to ask is there even a chance for me? I am willing to do whatever it takes no matter how expensive, time consuming, or shameful it may make me feel in order to get my license back, but I just wonder if I would even be considered and if so, would I be required to go back to school to refresh my skills and would it help for me to try to become certified as a nurse assistant in the meantime in order to at least have myself back in the field and even if that would be allowed. I'm sorry to make this so long and would welcome any advice or suggestions on this matter.

Thank you so much,

Robi
