Anyone else think that BPD can be beneficial in this way?

That it is a way of making problems less severe if put to good use? Should what it achieves be achieved by other, more healthy, means? Which?

I believe BPD creates some extra stimulation which is needed to prevent depression and mania. It might also "help" acceptance by creating (false) reasons for problems/failure. There must be a reason (or reasons) for the self-damaging and impulsive behaviour.

Is there a connection between schizoaffective disorder and borderline personality? One to balance risk-taking and -aversion and the other to undercut or partially prevent, SZA and in a different way balance the two.

Anyone else having schizoaffective disorder? Just to not make this into a BPD thread as it could be very much unrelated.
