Wow! Proud of you widgets!!!
I promise, it feels unnatural and uncomfortable, but it does start becoming easier after a while. Its like forming a good habit in a sense, doesn't take as much effort after a while.
And while I agree it doesn't feel good, you know what does? Being proud of yourself and rewarding yourself when you do manage to act better.
That's my tactic anyway
I've been practicing opposite actions for a while now, (not in DBT though) and it is realllly paying off.
I haven't directed a BPD *****fit at my bf since FEBRUARY, I'm now able to see when one is brewing and can usually diffuse it and opposite action helps me do this.
But when I can't talk myself into not texting something venomous to him, I say it to my Rage Journal instead and promise myself that if I still need to say it 24hrs later then something there is worth being said.
Usually if there actually is a message to be heard, its not at all venomous 24hrs later, because my inaction sparks introspection, so I'm able to identify what is behind the venom and address that directly, whether with him or with my T.
Sorry

I didn't mean to ramble, I'm just so damn proud of you and excited for you at the same time!
