Here I'll repost the original post. I hope you guys don't think too differently of me after though. BR's and hanksters post were helpful so I think I should leave it up for others. Even though I'm scared too.

"Okay I've been doing something for a long time. Well for almost two years since my PTSD stuff all came up. I have a tendency to run through scenarios in my head. I know everyone does that... but there more like worst case scenario bad things happening ones. I do it whenever I have to much time, mostly on bus/train rides or on walks. I tried to tell T on Monday but he thought I meant like normal ones. Then I emailed him today and told him he didnt get it. I elaborated a little more by saying they were one worst case scenario bad ones were I'm always trying to figure out how I need to react. He told me he gets it.

I don't know if I should leave it at that or actually tell him what kind of scenarios I'm thinking? I highly doubt he's going to ask. I feel really awkward bringing it up. I feel like there's something really wrong with me for doing this. I worry by telling him I'll just make it even more uncomfortable.

I have a session in the morning. I don't know what to do. I've kept this from him for a long time."
