I wanted to share what worked for me both before and after a formal diagnosis. 

I received my diagnosis approximately a year ago, and have had alot of success utilizing DBT etc for grounding myself when splitting. That being said, about a year before I started to see major improvements In my life/behavior by other means and still believe it helps me the most today.

**NOTICE, IM NOT HERE TO TOUT CHRISTIANITY SO PLEASE TRY NOT TO LOOK AT IT THAT WAY** 

I was however baptized Jan 2019, and regardless of faith/religions I've noticed logical explanations for the way my behavior was changed through seeking *something* greater than myself. 

The way I describe it is this:

When I put my faith in my friends, family, my coworkers etc, I am consistently let down and hurt. This set off chain events of spiraling and hyper analyzing my behavior and we all typically know where that leads. 

What changed when I started to seek faith in *anything* greater than myself (be it christ, Taoism, Islam, Judaism etc) is that they all have a running theme of "it is out of our hands". When good things happen to us, it is because it was planned and we should appreciate be thankful and give back. When back things happen to us, it is to force us to grow and learn. 
Most of the bad things lead to the best things. 

This mentality creates a sort of "win/win" by taking myself out of the equation. 

So yeah, I found this mentality that has kept me grounded to the point to purchase a home myself and return to college for teaching while maintaining healthy friendships and family relationships. 

Christianity might be off-putting for you, but if there is something you can chase that might be bigger than you I highly recommend it. 

*TL/DR* Things happen for a reason and taking ourselves out of the equation with any spirituality and using your DBT helps a lot.

I'm happy to answer and questions etc, just wanted to share my experience incase it might help somebody else.
