Check out some DBT / cbt techniques on YouTube or the like, whatever is easiest to access, find some that resonate with you and make them your own / tweak them so they fit your life / vibe.

I did a DBT course, and while I hated every minute of it, a lot of it is super great and hugely helpful for coping in hard moments and a great recipe for a way of living that's more calm and balanced. I feel like I hated the DBT course I did because the people presenting it had never even stumbled on a rock in their lives, let alone lived through a hard moment and needed any of this stuff for real, and their privilege read as saccharine condescension.

BUT! I'm never one to throw the baby out with the bath water, I believe you can turn anything to your advantage or upskill or just build knowledge, if you're industrious enough! You take those muthafking lemons and you make champagne, fk them. Plus they just mostly showed us clips on YouTube, so lol. The DBT course I did felt more like the break room from severance, having to admit how faulty you are and how this new enlightening thing they just told you seconds ago is going to benefit your life, as they announce each section. They didn't even give you time to process, let alone leave room for if that was something you already knew or already utilized, but, I powered through and just paid lip-service, got my upskill, moved on.

Easier path, just look up DBT on YouTube, find people explaining what you like, give it a go on a regular basis.
