I have been doing DBT from workbooks. I recently purchased a copy of Marsha Linehan's handouts and worksheets book. It's over 400 pages! I find when I am moderately upset I can use the DBT skills successfully to calm down. However, at times when I am severely stressed I can't calm myself down enough to use the skills. I just stay in my head thinking the same obsessive thoughts over and over.

I also have the habit when I am severely stressed to send emotional emails I later regret. This one habit really negatively affects my relationships.

Has anyone who has worked with DBT have any suggestions? What skills should I apply when I am over the top stressed?

And are there any suggestions as to how I can break the habit of sending emotional emails when upset?
