Thanks for all the replies!

I think I might tell my therapist when I see him next time (Friday next week). I don't know how to bring it up so I'm thinking about maybe writing it down on a paper and hand him the paper when I get there. Is that a good idea? By the way, it's not like he could hospitalize me or anything, right?

Also, I wrote that I sometimes worry I'll become really impulsive and carry out the things the thoughts "tell" me to do. Does that ever happen to you? Yesterday, for example, I felt compelled to put the nail against my left eye to see what that felt like (after I got the thought about pushing a nail into my eye). I actually held it against me left eye. I feel like I would never actually do anything but what if I get really impulsive all of a sudden? And now I'm thinking that sounds like an OCD intrusive thought but it probably isn't, right? It's probably some sort of suicidal thought just like the others.

It's confusing.
