Just Jumped Divisions...Will I Survive?

Hello all, I wanted to share some concerns about my recent jump in between divisions.

So, I've personally struggled climbing. However recently, I was finally able to overcome a hurdle I thought would never be possible. I jumped up to Plat. Considering I've been hardstuck Gold for so long, my joy in seeing that Plat icon on my profile has been short lived. My ability to climb divisions came from one of my personal favorites, . That being said, I can't ever imagine climbing any higher. To me, it feels impossible to climb even higher than Platinum, and I'm not sure why it's so different to me than how Silver > Gold or Gold > Plat felt. Not sure why I'm even posting this on here, but even tips for how to succeed in Platinum would be greatly appreciated.

Thanks for taking the time to read through this! Feedback is always welcome.
