I'm bp2 and these are just my simple examples...

Accusing my bf of the fact that he's going to meet this wonderful woman on Main road after work , immediately decide she's the one and promptly decide to marry her. Then call me to let me know and ask me to be his best man!

Yes, I believed this for 4 straight weeks, verbally/ textually abused him and harrassed him accusing him of all sorts of nefarious deeds against me (none of which were remotely true) until well after he refused to respond!

No paranoia btw, just this "truth" that I wanted him to admit to, so that I know where I stand.

The end of the 4th week, I text morning baby, blah blah blah... No response.
I'm thinking, bf is so quiet, is he stillll mad? Really?

What ever did I say that pissed him off... Look through my phone OMGEEEE Wtf was that? How did any of that make ANY kind of sense in my mind.

Where the eff did that idea even come from???
No clues, no hints, just a belief that popped into my head out of nowhere, and I clung to it like religion.

Delusional much Lia???

Grandoise? On a hypo scale ~ I'm better than everyone else, these people should be grateful I allow them to breath my air. Usually for me, present with alot of irritability, and with euphoria.

On a manic scale, I have no experience, so I'll have to go with Miss Laura's bout of mania when she was invincible (Grandoise) and walked into oncoming traffic to prove its true (Delusional)
~ Super dangerous, so glad nothing happened to her and she emerged physically unscathed.

Not everything is black and white, things don't present on specific scales and we don't all fit into perfect DSM molds, so the distinction isn't always clear.
To me, on my scale its;
Delusion ~ hell no effing way that's true
Grandoise~ Kiss my hiney and don't forget to thank me for letting you.
