Well if it ain't tofubutt!!!
You say you talk with your T. What if your appt is several days away. Do you have your T's phone # or do you wait until your next appt? Are you always able to wait that long? I talk about my ideation with my T too, when I see her. I don't have her # so a lot of the time I'm left to deal with it on my own. If you go for a walk and then come back and do something productive ie: laundry, is your thoughts different after that? The diversion works for you? Does it depend on what triggers the thoughts to begin with? What if whatever upset you to the point of seriously thinking about acting on your ideation was still there after your walk, then what? How would you handle that?
You don't answer your phone? Don't let my mom hear that!

I'm always getting told off about that and then someone ends up coming over here to make sure I'm ok. See, even they don't trust me. Can't say as I blame though, heck if they read this thread they'd be marching me straight up to the ER.

Someone needs to tell them I'm an angel.

jk, I know this is a serious subject.
