I am sorry about your daughter. I have not had issues with meds but when I was at Cleveland Clinic pain program which I was only at for a few days there were people who were. Part of why the program was not for me because a huge emphasis was going off meds,therapy around that etc and I did not face that plus my pain was too high. So I have heard of this being an issue with meds. Obviously with rsd some people need meds to function though extreme use and not under proper doctor care is not good. Is one doctor rx all those meds? Is she under the care of a doctor who deals with rsd and has she looked into other treatment such as ketamine etc? She has been employed as a nurse and on all these meds?
Divorce plus rsd plus change with job/relocation is a lot to face and I agree she needs more support mentally. Can you suggest her seeing someone? Also though I am not clear exactly of her doctors care it sounds like maybe another opinions to look at a different way of treating her. Could you suggest seeing a new pain doctor?
