MacBook Internal SSD Not showing up in System Information or Disk Utility

A couple days ago my MacBook, an early 2016, 12-inch, Retina model had a hard freeze, rainbow wheel and screen frozen. After a forced restart holding down the power button I was able to get to the login screen but my password would not work. After additional restarts I was greeted with the Flashing ? Folder icon for no startup disk. I tried it number of times, making sure I was not doing caps lock or anything of that nature. I was eventually able to get it running by installing macOS Mojave to an external drive however... The internal hard drive does now show up in anything: Disk Utility, diskutil list,System Information App > Storage, Recovery Mode / Only Recovery Mode etc. The HDD on these models is soldered to the board so I cannot remove it for further testing. Does this mean that my SSD is totally done for? Are there any other ways I can access it and test it? Below is my output from diskutil and some screen shots from Recovery Mode EDIT: The 319GB Drive is my external WD Hard Drive I am booted from, the CD sized drive is one of those built in partition on an external drive where the recovery software they bundle is stored. The Internal Drive is not showing up at all and should be 512 MB.
