Chronic feelings of emptiness.

People with BPD often talk about feeling empty, as if there’s a hole or a void inside them. At the extreme, you may feel as if you’re “nothing” or “nobody.” This feeling is uncomfortable, so you may try to fill the void with things like drugs, food, or sex. But nothing feels truly satisfying.
