You can also be born with Bipolar Type II disorder from the start but, yes, being raised by narcissists, groomed by a sexual predator or bullying in school or other environments will definitely exacerbate your mood swings. We definitely see this in Spinel and how she feels wasted and useless.
Basically, you can no longer regulate your emotions or moods anymore and your dopamine and endorphin production is fucked forever. There's literally no cure. It can never be healed or fixed, only managed. High maintenance girlfriend, etc.https://youtu.be/0-kennkvJLE
I know what you think of me
And how you say it's gonna be
Another won't come, leading you along
Or maybe you were wrong
No, I don't want you to go
But I don't know what other avenue is open to us both
Oh, what have I done?
Giving you my guilt only made me numb
I don't feel right
I feel like I wasted you
