Not sure how to word this one or really explain it. And maybe this isn't related to BPD, maybe I'm just somewhat of a hypochondriac. 

I feel like I'm always super aware of my psycho-physiological state, especially when I'm imbibing substances (like drinking or getting high) and I constantly notice shifts in my mental state, or my physical state. How to word/explain this...

Like...

I'll be watching a show that makes me laugh and I'm feeling good, then my girlfriend comes in and makes a negative comment about something unrelated and I immediately feel/notice/focus  myself feeling really bad. 

Or... crap I'm just really struggling to think of ways to articulate what I'm saying. 

Ok, like maybe I'm playing a video game, feeling pretty "normal", and suddenly I feel my body temperature rise (idk) and I feel my face flushing. I IMMEDIATELY notice it, hyper focus on it, then start stressing about wtf is happening to me. 

God I know I can think of/articulate better examples of what I'm trying to say but I'm struggling right now. 

Does anyone relate to what I'm trying to say?
