I think I should make it clear that I don't have BPD. I have struggled with BPD like symptoms, but I don't meet the full criteria for a diagnosis. 

I have a good grasp on what all the other symptoms are like (identity issues, impulsiveness, suicidal thoughts etc.), but the only symptom I have trouble understanding is "chronic feelings of emptiness". What exactly does it mean to feel "empty"? 

What I want to know is what exactly this means.
