I have a history of self-injury but I don't injure anymore. Does anyone know if this will prevent me from getting the surgery?

It didnt stop me. I had the psych evaluation and was totally afraid to say it but totally honest anyway; I was a cutter in HS and severly depressed (I was adopted so I later found out that, that runs in my family), anyway I was told by my psych that I seemed to have a good grasp on the realities of life and that my faith has obviously been a means of healing for me mentally. I haven't taken meds in years and she cleared me without any issues.

Hoping for the best for you as well
