I feel that saying 'severe issues' is too much. She's clearly still a strong person who can enjoy many things in life - books, wine, yoga, etc.
And the very fact that Jill doesn't yet forgive her when you're on Bella's path indicates that her mental state can't be that bad - she wouldn't do that to a broken Bella, would she? Especially since Bella herself mentions her past when trying to get Jill to forgive her.
As for the quote about calling for help, I attribute that to DPC's signature exaggerated drama. Yes, Bella might benefit from seeing a therapist to help her heal some emotional pain. But I think that's the case with many people in this world.
