I hope that your T is going over what skills you tried & what didn't work & WHY they didn't work....so that you can get a deeper insight into yourself. Think that if T can go that deep inside of yourself, he might get a much better picture of what's going on with you.
DBT is to teach us that the ultimate control is OURS. Yes, it's important to have a support system when we are struggling but sadly, the ultimate responsibility is our own to take care of ourselves. Know it's hard when we find that hole we slip through....hopefully as you progress with your DBT, YOU will be able to fill those holes with your own skills after you learn what they are & how to use them.
Hopefully if something like this happens again, you will be able to look at the big picture (that being what can happen to you when you feel that way) & figure out what the emotions are that you are feeling that are causing you to feel so out of control. Once you understand your emotions, they you will be able to do something about them with your logical thought & come up with a much better way than SI of dealing with what you are feeling.......ah, the ultimate purpose of DBT....but it takes quite awhile to get there......I have been going to DBT since last January & still am working on figuring it out......even our leader who has been teaching DBT for years says that there are days when she can't even follow the DBT skills...but at least she recognized what she is doing....sometimes I can't even get to that point yet....but it will come with practice. Your T sounds awesome going over the chain reactions that happened.....this is in order for you to learn from what you did through his guidance.....think that is a wonderful process
Sending you my best wishes
