I was diagnosed BP but don't take meds for it, I don't have major mood swings.. long story
I mean honestly man you're still so young that I question if you're even calculating your symptoms correctly
I am not trying to downplay your symptoms or say you aren't bipolar, not at all, I'm just saying you're at a such young age that it's difficult to really diagnose anything...
Get sober, eat healthy, exercise, have therapy... see where you are in a few years
your brain is not even half done developing, you will likely feel a lot different in 7 years from now
just stop thinking it's doomsday or you have permanent damage, you're still a baby man, your brain has 7 more years before it even begins to be completely developed
