So I've known I've had BPD for about a year but I still get really confused what splitting js exactly. First it was of having no control over emotions and they are off the rollar coaster. Second it was a mechcanisim for self defense for myself. It is also just waves of emotions that last days to weeks. I don't know what splitting is exactly, and yet I can tell I am some times but can never pin point it. What is it to you? I figured there are a lot of definitions but just one would be nice to go on so it wouldn't be so hard to help focus to be better about it.
