I hear you For me personally though, its not the mood swings that are exhausting, probably because I'm bipolar and don't know any different.

But for me what I find utterly exhausting is challenging my negative or paranoid thoughts. Catching myself AND stopping bad behaviour in its tracks. Talking myself down, on sometimes a daily basis, because I know it will just rock my love boat.

I promise you I have narcolepsy like symptoms every 3 months that last for about a week, where I have been known to pass out mid convo I'm sure its all this leashing I do daily...

Anyway, all I meant to say is I do get it...
I ramble, quite often
