I just spent so much money on my car and now a week later something else broke. 
That's terrible.. There's nothing more frustrating and deflating in life than unexpected expenses. I hope you're able to cover all of it. I know if I had one right now, I might not be able to manage it.
I honestly don't know where to get money to fix it, i'll probably try to fix it by myself
I hope you can. If you think there's even a chance, then give it a shot, if it will save you that much money. My brother watches Youtube videos all the time of how to fix random things, and it seems to work for him. If you're the type of person that can learn that way, and if you have the patience, then I think it's a good thing to try.
