I have talked to my T about it some--you're referring more to ideation here, right? (I've seen SUI used to mean a couple different things.) At one point, I felt like he wasn't taking me that seriously, like he never thought I would do anything. He said that he does take it seriously (but never felt I was at risk for acting on it). And that he understands how painful it can be for me to have those thoughts. It helped to hear him say that part. He also said it seemed like I tended to tell him after the fact, like "I had these thoughts yesterday" rather than when I'm actively thinking about it. I feel like they're more likely to come up at a time when I'm not in session, and I'm hesitant to share them in an email because I don't want it to seem like I expect him to reply right away or for him to misinterpret that they're just ideation.
