I've posted this before, but can't remember if I directed it at you.
You need to rethink your attitude to money.
We basically have three types of expenditure. Capital, essential and luxury. (There are more, but for here, these will do).
Capital is what you must spend to earn more.
Essential is what you must spend to survive.
Luxury, in this example, is everything else.
You need car to earn. So it is capital. But, you don't need a more expensive car than is necessary. Equally, a really cheap car or one that costs a lot to run is wasteful. You buy a car that is reliable, efficient and at the lowest price. Also, take care of it so, when the time comes, you can sell it.
Essential. You must eat, attend to your health and pay your bills. But you can save a lot here by cutting back. Don't go out, buy cheaper food and essentials, provided the quality is good enough, and always pay your bills. But turn off lights, Get a lower rent apartment and so on.
And don't give up, never give up.
