Like, if I think for too long about someone I dated 12 years ago, I'll start getting upset and feel just as bad as when we had just broken up. 

I find that when I love someone, I always love them.

It also works like that for people who have bullied me in the past. If I think about too deeply it brings back all those old feelings of shame and hurt.

Anyone else get this? Is it BPD or just me?

Cheers
