GTA Online single-handedly destroyed my game

[GTA Online single-handedly destroyed my game]

Alright, I did now.

[GTA Online single-handedly destroyed my game]

Alright, so how exactly do I do that?

[What's your top speed?]

Michael - 118 MPH in a Coquette

Franklin - 142 MPH in a Jackal

Trevor - 122 MPH in a Cheetah

GTA Online - 111 in an F620

Pitiful, I know,

[Interesting things you've come across in the Ocean or Underwater]

I found the crashed Merryweather Cargo Plane that Trevor abandons after it starts going down. It's in the Pacific, you know, near the Sonar Collections Dock (Something like that) near Paleto Bay.

[What are your favourite Sports/ Muscle & Super Cars?]

If this were a question of favorite car in the game, I'd say Fugitive. After making it my car in GTA Online, I've just grown... attached to it.

[Things you dislike in GTA V]

That GTA Online has so many bugs and glitches. Also, that it somehow messes with your main game.

Yep, it's not a problem with my console. Although Fallout: New Vegas freezes a bit, but I mean, it's Fallout: New Vegas. But yeah, all my other games work perfectly fine.

[Things you witness when switching characters]

My favorite one as Trevor was switching to find him waking up, laying on the Railroad tracks with a speeding train approaching. Forgot exactly what he said. I also keep finding Michael walking by a bunch of hookers, telling them he couldn't, because he was married. What I wonder... is why he parked his car right by there, just to tell them that, no, he was married...

EDIT:

Just recently switched to Trevor (In my broken, broken game), being chased down Olympic Freeway in his Truck, by a bunch of cops. He had a two-star wanted level.

Well, let me start from the top. I've completed the whole campaign, and some of the Strangers missions. I've been playing GTA Online now. Then, yesterday, on the 4th, it just goes 'Poof!' (Not literally), and decides to not work anymore. Let me clarify. All of the text in my game is gone, the closest thing to text I get is the startup screen saying incredibly useful information such as "TOOLTIPS_56" and "TOOLTIPS_41". I can't start missions anymore (By which I mean strangers missions). Also, when the game starts up, it often just freezes at the part where it tells you "Do not shut off console while the Saving symbol is shown" where there's really only the symbols, because the text is gone, as I've said before. I've tried deleting the Atomic Blimp DLC, Deleting all my saves besides the autosave, Deleting the game and reinstalling it, cleaning the disk as thoroughly as physically possible, restarting my system, unplugging my system and plugging it back in after 30 seconds, Deleting the update and reupdating, and even just trying to play through the game in it's current state. Then, hopeful as ever, I start up the game, and, what do you know, no luck. I've got an Xbox 360 (The Black one, it has 200 GB), it still has about 146 GB left. What exactly can I do'? Any suggestions? Anyone else have this problem?
