I believe I have bricked my HTC One Mini 2?

Was at work using both my company phone (iPhone 5) and my personal phone (HTC One Mini 2) just fine. Put my personal phone away to get on with actual work and came home at around 5:30'ish. Played a bit ("a bit") until about 9/10pm (I think?) whereby I looked for my phone to just check things like WhatsApp and Snapchat and the phone wasn't turning on when I was holding the power button. I just thought to myself "huh, the battery must be dead" and put it to charge and the charging LED (as well as the charging screen with the "do not distribute outside htc blabla" dev screen) displayed so I just assume it's charging as per usual. Fast forward to about 1am, I have finished using my computer and decide to hop into bed. I go to turn on my phone by first powering down with power, vol up and vol down (as usual) and then try to boot the phone up. It boots as normal up until the O/S loading screen with a pac-man boot animation (I have PAC ROM installed) whereby it will freeze on the "game over" image of the boot animation and then proceed to go to a black screen. I thought to myself "hm, must be a mistake or something" and try it again to no avail. So I then go into recovery to do a fresh install and I try to wipe the phone and I do a factory reset in twrp, but upon trying to format data, the progress bar doesn't move (and so I left it overnight as I couldn't be bothered to wait). Upon leaving it overnight (1am to 7am) to format the data, I wake up to see that the progress bar hadn't moved at all from 0%. I then just thought "maybe the phone has actually formatted it but hasn't updated the image on screen so me being the dumbo I am, decided to force shut down the phone (with power, volup and voldown) and upon trying to boot the phone up again, it displays the HTC logo with the red writing, tries to boot into the O/S, fails, and then tries to boot into recovery and gets stuck in a boot loop (it will show the twrp logo and then a black screen, twrp logo and then black screen etc.). I have tried to flash twrp again (without first removing the twrp currently on it) but I was wondering what I could do in this situation. I am able to access the bootmenu (for hboot and fastboot) but nothing else.

TL;DR: I think I bricked my HTC One Mini 2. Came home, charged phone and phone got stuck at boot animation. Wiped phone in recovery, it got stuck on formatting data and now It can't boot into the O/S since it's wiped and it can't boot into Recovery for whatever reason.
