Hmmmmmmm.... from what I can tell of dbt, it isn't really to get in touch with your emotions as much as it is to bring them up in that moment and then release them. Wait, I might be confusing this with emdr.
Anyway, i quit a job where i couldn't be safe. I was cutting and eventually cutting on the job... and then cutting about 5 feet from my boss, with customers in the store. It was like family - and just as disfunctional. I had to get out of there. You're trying suicide there needs to be looked at; was it in conjunction of the job? Were you sooooooooo unhappy in your job that you needed out? Or were they not related? Did your work know you attempted? is that your concern? Can you say more?
