Great question! For me, the short answer is yes. I would hope a thought out attempt would be such as far as thinking of family,friends,pets,children..etc. now a impulsive attempt, to me, is where one had a really bad experience right now, or someone said/told one upsetting info, or just a knee jerk quick thats it I am done. Now, just last week for me, i started a new job on 10.05 and was fired on 10.09, yep 4 days on a new job and was told that i was not getting the training quick enough for their standards, and I was told nothing before hand at all. For a couple of minutes I was 90% ready to ctb. BUT by the time I had driven home, around 15 minutes, i started picking up my mental pieces and putting it in perspective and said to myself "thank heavens that i am the hell out of there!"
