Pokemon Heartgold Nuzlocke (Final)

I don't know where to even begin. Well, I'm going to make it brief and just describe the Final moments because I'm feeling just a little defeated.
So after doing everything, I get to Blackthorn and go to the Gym. Prior to the gym though, I farm coins at the Voltorbflip game and get Manana Ice Beam. I was super stoked and felt confident. Got all the way to Clair and surprise, a Gyarados. I don't panic and just use Amnesia while Gyarados uses Dragon Rage and after doing no damage, I get to Kingdra. Does 22 points to Manana's 139 Hp. Then it realizes that and uses Smokescreen. Pretty annoying. She uses her last Hyper potion and out of nowhere, does not make sense, the math indicates that this shouldn't have happened. But Manana faints from Kingdra's Crit Hydro Pump despite having 86 points of health and 3 Amnesias. I panic and feel that this is the end and send out Fraunky, she does a miracle. A Pysbeam crit and confusion, Kingdra misses and Fraunky gets us the win. I become emo. None of my favorites are alive and I spent 12 hours for Manana to die with Ice Beam. I hear about the kimono girls and go to the place. I realize that I've made a mistake by accidentally walking into a gauntlet of them. They're all lvl 38 and my highest is 35. I know that this is the end. I got careless and thought it was like the originals and fluffed up for everyone. Umbreon goes down quickly with no casualties but then comes Espeon. This Pokemon destroys everyone. One after another I have to say sorry to my dying pokemon. It was all my fault. Looking back, the game did me the ultimate injustice but gave me a freebie. What I did then was on me and not the game's fault. I failed them all and can't apologize enough. It was a good run but boy did this run feel rigged. GG Heartgold, gg...
