Having experienced a decompensation, if you mean anything like that, it is not something you would want to do. It could be almost irreversible.

As for speaking things outloud, I have found that, not having anyone to speak to, what matters is if I can "speak" it to myself -- if I can formulate the ideas to myself. I cannot always do that, but if I can, it is almost as good as having someone who listens. I have found T's I know always interrupt my thoughts, so doing it by myself in some quiet time is the only way I have of getting at my thoughts.
