That's part of BPD. And learning to regulate those stong emotions is not easy. There is a DBT Workbook available on Amazon that has helped me a lot with this, even in the absence of a T trained in the technique. If you are not familiar with DBT you can read more about it on this site. One of the hardest things that I had to learn was that I needed to change my behaviors, not expect people to accept them because "that's just how I am". Lots and Lots of hugs coming your way from across the pond.
