Im pretty newly diagnosed with BPD and am largely still trying to get my head around the moods etc

I had a blazing row with my partner last night, which was over something so petty but has now left me questioning whether I was right or not, or was it just my moods kicking off again

I am now feeling that 'empty' horrible feeling, does anyone else get this after arguements? Is it a reaction to the harmony being disturbed?
