Not anymore.

Do you mean a "braless" prison?

Where I live I keep it on lockdown.

For many years, I was stuck in a bad marriage, and felt like a prisoner. I remember referring to my state of mind as "my gray little cell" and I wrote poetry and songs expressing my desire to escape it. Finally my opportunity came for me to run and I did. I have no desire to write poetry anymore, as I am happy. Never looked back.

So, for me, it wasn't my own mind so much that was the prison, but the situation I was in. I guess, in a way it was my own mind because I was following some sort of decorum regarding how I went about my escape, but still I just had to act a bit out of character to achieve my freedom.

Sometimes we don't see our options, or act on them, because we have imposed a certain set of rules upon ourselves, what is expected of us, or what we've been taught. The best advice I can give anyone who is feeling like they are imprisoned by their mind is to try to be true to the inner you and devote yourself to what will give you happiness, and set about making those circumstances happen.

I'm not sure of your reason for posting this question, but it kind of resonated with me.
