Thanks for getting back to me ManiacalFairy!
One can learn the DBT skills through reading online... .we have several articles and workshops on DBT and there are websites to help guide daily practicing of skills. There are also workbooks that you can purchase and do on your own. Many of these skills will help you to learn to slow down your reaction time and respond in more helpful ways.
There is a very good resource to learn validation and how to ask validating questions. The Book "I Don't Have to make Everything All Better" by Gary and Joy Lundberg is excellent (and cheap used online). We also have a lot of info on validation and workshops here to help. Funny thing is that when we have a skill to replace our previous "reactions" we often times see our kids doing the same... .being heard and understood can be very soothing to those intense emotions of theirs and that creates the space for them to use their skills.
