OK, now we're making some progress.
The "soil" looks like a bunch of rocks.
Excellent! All too often we read on these pages of trees in what amounts to little more than peat. The "rocks" are one component of a proper bonsai soil, you just have to learn how to manage it properly.
I know that it has holes in the bottom of the pot because I tried to water it like all of my other plants and it just ran out of the bottom.
Again, this is good news but I'm a little confused on this point. Later you wrote:
I mist it (because that is what I was told to do). I do that often..I just get it wet and then I do it a few times a day (if I can remember)
Misting is fine but it is not a replacement for thorough watering. Have you read the sticky yet? If I understand you correctly the tree is dry due to lack of watering. I take it you are at work now. Does your office have a kitchenette? if so take the tree to the sink and immerse the tree up to the rim in water.
Avoid chlorinated water if possible, use bottled water, but water it well regardless of what you have available. Allow the tree to stand in this water until the soil is thoroughly saturated and then drain the sink. Do not allow the tree to stand in the water for an extended period of time, certainly not overnight.
This is an emergency measure not to be used on a regular basis. Proper watering is normally done from above until water runs freely from the pot and then repeated several times. Another reason that an office is not ideal for bonsai.
To me it all seems really dry but I have only plants, I am used to soil...
Since your tree is potted in a free draining soil mix more frequent watering will be required than other potted plants that you may be familiar with.
My office is bright and shiny. It is only place that I can keep my plants.
Use the search feature of this site for the term "humidity tray" this will help keep the micro-climate near the tree a little more humid.
