I'm sorry you feel down. I have hit my own face in anger too, numerous times actually, so I can relate. If the bruises are still there, make-up should help make them disappear.

There is a helpful DBT Workbook by Author Matthew McKay. I purchased it at Barnes & Noble for around $20.00. It will make a difference. IF you do the work. This book is used, and handed out by professionals in DBT classes. Sure it won't fix ALL your problems, but it would be a good start if you don't have it already.

Hope this helps!
