This is the discovery process that psychotherapy provides for us
It takes time. There is much to learn. Just learning how to slow down thoughts to try to see where the overwhelming feelings begin takes time, practice, help.

Maybe for now it would be helpful to simply accept those feelings. They are real and valid. You feel them. They are yours.

Do you like to read? I liked reading more about BPD. "get me out of here" by rachel riland was a good book, an account of her experience with BPD from hospitatization through her successful therapy.

Are you getting help through psychotherapy?
