My T reacts similarly sometimes. We have talked about such thoughts ever since I first started, so it's a topic that comes every few weeks, if I don't say anything he asks about it. But he doesn't always ask in detail if I mention them. Sometimes he does, sometimes he doesn't. I think it has to do with how I talk about it. He usually knows to be concerned if I don't show any emotion anymore. Then he'll ask about plans, means and so on. If I cry, he might quickly ask about it, but then try to explore why I'm crying about it.
