First, ofcourse, you do have to call your mother, explain the issue in clear language, control your cries and tears and she probably will call the computer tech guy or pull you from the computer and never let you use it at all. Don't use the internet anymore, you might break something.
Go to your local computer guy or call him so that he could fix the issue by you having to pay him money. Why, what, the game giving you all possibilities at earning money and items was not enough, so you just couldn't help yourself, but to start cheating? This is not the way to play the game, especially when you don't know how to use the computer. That's right, you're a cheater and you bit into consequences you won't be able to chew. Most likely, due to your poor judgement, you have installed a virus on your computer by having an urge to cut short and use cheats in GTA Online.
Your high-end gaming PC doesn't matter when you have no skill at traversing the web.
