The living room fiasco through the years

I should probably say right off the bat that I hate my living room. I have always hated this  living room. 9 years and counting I have mostly hated this space.   There are a lot of reason. I hate my sofa. Sofas. Whatever. I hate the fake fireplace wall. I hate the lack of usable wall space (there is NONE) and I hate the shape of this room. It's 14 ft wide, 19 ft long with an angled fake fireplace wall. The carpet is gross and the ceiling is worse.  The windows are huge though, and the view is nice.  Not an equal trade off, but it's something.
 So, here it what it looked like 8 years ago. Please remember that I had a new baby, just had a horrid car crash AND was battling cancer. The LAST thing on my mind was decor. It shows.

The little baby on the couch is now 8 1/2 years old. 

When I finally did something, it was this. Above and below. New rug, covers on the horrid sofa. I painted out the atrocious fake wood paneling. We changed out the door.  This looks more like a play room (and it was) than a living room.  Above was the "winter" look, below, the "summer" I love that sofa- it's in my basement now, but it CLASHED with the wall cover something awful......

Then I did this. Now, this was the basic look I was happiest with, but the sofas we falling apart. 

and the chairs were very uncomfortable. Also, the fake fireplace was giving me migranes. It was cold and didn't work right. 

Then, we had picked up a lovely vintage sofa for cheap and it had been in our living room in the basement. We moved that upstairs when it became a better "sit" than the sofas upstairs. It died in about 18 months upstairs and I was left with chairs..... 

Then, we got an offer from my Aunt about a year ago. She was getting new furniture, did I want her old stuff? It was nice, comfortable and free. But it wasn't my style at all. I took it anyway. I call it a land barge. It's a HUGE 8 ft long 4 ft wide pillow back tanker truck. It's great for sleeping though, and for making pillow forts.  

The pattern is distracting. But the colors are good for this room. But I have no idea what to do with this room. It's not the sofas fault. It's my lack of vision. It's dull, and boring. Way too rustic cottage-deer shack  even for me. 

This is how it looks right now... 

Just to know, I am going to paint this room AND that new wall behind the sofa this winter. It will be a darker green than you see here..... 

This wall is giving me headaches. I took down the shelves that were there and threw up some pictures, but I need a plan for this wall..... (above) I liked the shelves, but they were dangerous with an 8 yr old boy and his friends and nerf guns and well, you get the picture. Safety first.

See just how little wall space I actually have? 

Below is the cat area. That's why there is a large piece of wood next to the desk- scratching post. She likes hiding in the ferns and sitting on the desk looking outside....

does anyone have any brilliant ideas?  I am all out.
