I'm still very new to bpd, so I thought I'd ask if anyone can relate. The way I carry myself at one moment doesn't match the way I'd act an hour later at all. For example regarding the amount of personal information I share, the opinions and values I have and the way I talk. It almost reminds me of my friends complaining about feeling guilty and ashamed after a night out drinking. I relate to this on a daily basis, just without being under the influence of any substance. 

I'm deeply ashamed of what I've considered "the way I am" an hour ago, even though I was so sure of it back then. I don't even recognize myself anymore. I spend wayyyy too much time on regretting every single move I've made because everything is so far from how I'd like to present myself now. I'm shocked at what I used to put effort and time in, was interested in, or considered important. Does anyone know how I can stop obsessing and feeling guilty about insignificant things I did just because my identity does literaly 20 full 180s a day? This would be so much easier if I could manage to care just little bit less or realize that the amount of shame I feel is completely irrational.
