Many different personalities, combined together makes one person. And each personality; probably is a symbol of every emotion. The personality becomes an alter, when she goes beyond her emotion. If you suppress her, trying to control everything, eventually, gradually things start spinning out of control. If you do not take care of her, you will be punished with a lifelong pain.
Such a mess it is: both wanting to control and letting go of control.
Life-long commitment with you now.
