My camera is in M mode, I'm not letting myself take it off until I learn it!

Here is what is happening....
I will set the f stop, speed, and ISO until the meter says everything is correct.
This is the mistake. I am guessing when you say "everything is correct" you mean the exposure meter is in the middle? This is hardly correct. You are still allowing the camera to make the decision in what is the "correct" exposure. You realize if you are in M mode and you always set the exposure meter to the middle, you are essentially in automatic mode right?
Once you get this concept, I am 100% sure it will open things up for you.

I will take a picture, then I turn a bit to the left, or turn around completely (same room) and suddenly the meter says its not correct (because things such as windows are throwing the meter off), so I adjust speed usually, sometimes ISO.
Window light is one thing. Let's take a simpler example. Assume there's no harsh directional light coming into the room. Let's say the black dog is "throwing the meter off". Think about it. Has the lighting changed? Nope. What's throwing the meter off is the darkness of the dog relative to neutral gray. The camera will see the dark black dog and think it needs to overexpose to compensate for it. The problems is, the lighting never changed, just the subjects color. Same thing with a white dress. It's bright and the camera thinks it needs to underexpose. Again, an incorrect assumption by the camera.

I try to do it quickly so I don't lose the shot (this is where I start to get really flustered). What I get at the end of the shoot is pictures that are all over the place exposure wise. Most being too dark or too light. Every single one has trouble areas, such as a face being totally dark, but a white shirt being very bright. I try to adjust this in LR, but its exhausting. I would much rather get the proper exposure in the camera and then do minor adjustments.
Shooting into window light will always be problematic if you are doing things quickly and you are going from room light to the harsh directional window light. With experience you will know how much to compensate for it, but it won't be instantaneous. It also depends on what you want to expose for. Expose for the window light if you want a silhouette. Expose for the subject and you will blow out the window light. If you want to expose both properly, expose for the window light, and use fill flash for the subject. There are many ways to skin a cat.
My rule of thumb is, if lighting is consistent, then shoot in M because you don't want things like color of clothing, glare from glass or shiny objects, etc. to throw off the camera.

So I should meter from a gray card, and then leave the camera on those settings unless I completely change rooms or go outside?
You can, if you have the time to take readings. Check your histogram has well. Not always helpful, but most times, it'll tell you what's happening with your exposure.

Ahhhh! I'm already confused! How do I know the background is exposed properly? Just by looking on the screen? I still get pictures where the background looks normal, but those extremes I'm talking about still look awful in the picture. Example of this is outside. The grass will look properly exposed, but (in this instance) the black/white dog looks way too dark (black head) or too bright (white body). I'm sorry if I sound really stupid...but this is where my original post started. I get really confused and it's hard to type out exactly what I mean.
You have some margin to adjust these things in post processing. However it sounds to me like you perhaps need to investigate using fill flash.
A perfect example is shooting someone with the sun on their back. So you are shooting INTO the sun. You expose for the sky and you underexpose the person. You expose for the person, you blow out the sky. There's just now way you are going to get both things with correct exposure. In this case, you have 2 options.
- Bracket your shot then merge in post.
- Use fill flash. So you would expose for the BG then use fill flash for the subject.
