Belarus has BPD.
By BPD, I mean Borderline Personality DIsorder, not Bipolar Disorder. Note that I don't have BPD, so this is based on research I've done.
A lot of the symptoms do remind me of her--fear of abandonment, unstable interpersonal relationships, impulsive/self-destructive behaviors, unclear or shifting self-image, mood swings, chronic feelings of emptiness, explosive anger, and paranoia.
I classified her Russia obsession as fitting into three of the above categories, but it honestly does reveal a fear of abandonment, the unstable interpersonal relationships is obvious, and I believe her Russia obsession should count as at least somewhat self-destructive.
This doesn't mean I think she's a bad person--I don't. She just currently is not getting the support she needs.
