OK so here is where my risk to harm assessment plays out:

You spend time in and out of therapy working diligently to break down your many layers of defenses, access your deep seeded emotions and start sharing them with your T. The fact that you've been working with this T for a while has made this possible. However you are still really uncomfortable. You are in a new type of relationship that seems kind of safe but it is unfamiliar territory. Your are not really sure what the new rules and boundaries of this therapeutic relationship are (i.e what should be shared, what shouldn't be shared, how angry is too angry, how weird is too weird, etc.). Unfortunately as you break down these old defense you unleash a raging river of emotions that have been dammed for decades and under high pressure. When the dam explodes and you loose all emotional control. You T may be able to deal with this in stride because she just has to deal with you for an hour. But YOU and potentially others around you who are not accustom to this have no tolerance for it. Instead of floating and riding it out, you simply drown and take others down with you.

Is it worth the risk? What are the real benefits if you succeed and don't drown? Wow you can cry in front of friends, you can share some freaky childhood stories, you can genuinely express grief or happiness extemporaneously. Is this all worth it? Mouse doesn't seem to be in a very good place right now. I hope what she is experiencing is over quickly for her.
