I don't know if this possible but since 2 years ago I began to have moodswings (am 20 now). Recently my mental health has been declinging. About a month ago I had all of the criteria for bpd. At this moment I don't have them all and have more criteria of npd /aspd . Is it possible to have like a disorder where you switch between personality disorders??? It makes me go crazy actually because two weeks ago I had massive empathy for people and now i have none wich is scary. So I'm wondering if this is possible. I hope this makes sense because English is not my first language. Thanks in regards!
