Texture Shaded Dark.. Unable to see anything
So when I'm using texture shaded mode, it is literally pitch black and I can't see anything. There is no roof on the place that the camera is inside, it's completely open above.
Example:

How do I make it so I can see?

I suspect you have the headlamp turned off, or you have a light loaded that isn't affecting the area in view (a spot light pointing away, for example). Try hitting ctrl(Win)/cmd(Mac) L to turn off the previewing of lights and give you the headlamp back.
Thank you!!
