Idk if this is a BPD thing or something else entirely, but sometimes I just don't feel like acting like a "normal" person. I just kind of shut off any unnecessary social normalities, because I just don't care about appearing to be normal for the day, or possibly even longer. I know that with BPD mimicry is a common thing, a lot of us learn to be like other people to fit in more, but sometimes I just stop caring and revert to what a nt person might consider almost like a hollow shell. I still have my interests, and I'm still feeling things, but I just don't feel a particular need or desire to display that on the outside
