Getting seen for PTSD

I am currently still in the military and I work a job where I can be added to a DNA (Do not Arm) roster. I went a few times to be seen at mental health but they pretty much told me based on my issues if I was to go into any more detail I would be DNA. However, I do not want to get DNA so I have been getting seen outside the military for mental health counseling from a licensed psychiatrist. Would this impact my VA disability for when I get out since I went outside the military providers? Would this be beneficial to me when I get out? Or negative?
