Hi diffey_09

I'm sorry to hear about your breakup and the loss of your grandmother. It is so difficult to lose a close romantic relationship. If we add BPD to the dynamic, and a dying relative, it can be so much harder. I can definitely relate, as my father died right before the final breakup with pwBPD.
Your feelings are really understandable. It makes sense to continue to love and want to be with someone, even if they've hurt you. The members here have been in similar situations, and understand what you are going through.
Since you have depression yourself, have you been seeing a therapist to help you through the grieving process? Do you have supportive friends and family whom you can lean on? It's very important to rally as much support around you as you can. I'm glad you reached out to this site—we can be your virtual support system.

Are you still in regular contact with your girlfriend at the moment?
Keep writing. It helps to share. We're here for you.
