I am a bit bothered by what you just said.
In one sentence you say you were put on medication to control your mental illness. In another you say it helps you accept being owned and Dominated.

I don't have a problem with people taking medications for any sort of mental illness, what I do have a problem with is taking a medication to help control something that your mind can do anyway.
I do know that some people need to take medication to control certain thought patterns or behaviour, while others can do so through behaviour modification, sometimes using medication only for a brief period of time to help out.

I don't know what your mental illness is, and if you don't want to divulge that it is fine.
What I do see though is that you are taking medication because you have a problem accepting the fact you are owned and controlled, and someone else is allowing this to happen.

I have issues all of the time with being owned, and being used as an object for someone else's pleasure. I wrestle with the thoughts of how I can allow someone to objectify me, use me, and I crave it.
To me it seems wrong somehow to enjoy being treated badly, but I don't allow it to destroy me by thinking it is wrong.

If both of you enjoy and accept this, why is it hard for you to accept it without medication?

Please don't take this post as an attack, I am merely curious as to why you said what you said.
